UPDATE:  Vanilla, no mods no sandbox (expect minimap)   Additional serious vanilla animal/base bug findings (Build 42, singleplayer, no mods, default sandbox) I am posting this as a follow-up because I have now encountered multiple serious issues in a fresh vanilla singleplayer run under clean conditions: Singleplayer No mods Default sandbox settings Completely separate new save I was also running with -debug during this test run, but there were no mods and no custom sandbox changes This is not my old migrated save. These findings are from a fresh vanilla run. 1) Cross-species parent/baby relationship corruption I have multiple animal zones on my base. These zones do not overlap and are not intentionally merged. One specific zone originally contained pigs only. Later it contained: 1 ram 1 ewe 1 bull 1 cow calf 1 mother cow linked to that calf 1 additional adult cow Separately, there is also a neighboring chicken zone. At one point, an animal in that sheep/cattle zone damaged fencing and the ewe temporarily got into the narrow space between the sheep/cattle zone and the neighboring chicken area. The ewe did not fully enter the chicken zone, but it ended up near the border after the fence break. Later, when checking animal status, I found that the ewe had a baby reference to a Leghorn chick. I then moved the chick and confirmed the behavior: the ewe recognized the Leghorn chick as its baby the chick recognized the ewe as its parent/mother the chick immediately ran toward the ewe with normal baby-follow behavior So this was not just a UI display issue. The incorrect parent/baby relationship was actually being used by the animal AI/behavior logic. This means I observed a cross-species / cross-zone parent-child link: adult sheep ewe baby chicken (Leghorn chick) That should obviously never happen. 2) Animals randomly bashing fences without an obvious valid reason In the same general area / animal setup, I also had cases where animals started bashing fences even though there was no obvious reason for it. Examples: earlier in that zone, one of the pigs suddenly started destroying fences later, after the pigs had already been moved out and only sheep/cattle remained in the zone, one of the cows also started bashing fences When I checked the cow in debug, it only had minimal stress and otherwise looked fine. I did not see an obvious condition that would explain aggressive fence destruction. I cannot prove whether this is directly related to the parent/offspring corruption, but it happened in the same save and same base animal setup. 3) Feed trough contents appearing to convert into water I also observed strange feed trough behavior in the same fresh vanilla run. These were metal animal feed troughs (capacity 100), not player-built containers. I moved them from farm properties and used them in my base. What happened: one trough had grass/hay stored in it another trough had animal food sacks another had a small amount of feed/hay a fourth one was empty Later I found that some of the troughs that had contained feed now showed water instead, while the empty one remained empty. Important details: these troughs were outdoors without a roof above them however, I did not notice rain at the time in these troughs, I cannot mix water and feed; it is effectively either one state or the other I do not know whether this is intended trough logic, a weather interaction bug, or something else, but it looked suspicious enough to mention because it happened in the same run as the other animal issues. 4) Crash in the same fresh vanilla run when returning to base The same vanilla run later crashed when I returned to base. The crash was not a Java heap out-of-memory this time. It was a repeated renderer exception: java.lang.ArrayIndexOutOfBoundsException: Index 897518 out of bounds for length 897518 at GenericSpriteRenderState.NewFrame(GenericSpriteRenderState.java:188) Stack trace: zombie.core.sprite.GenericSpriteRenderState.NewFrame(GenericSpriteRenderState.java:188) zombie.core.SpriteRenderer.NewFrame(SpriteRenderer.java:139) zombie.GameWindow.renderInternal(GameWindow.java:441) zombie.GameWindow.frameStep(GameWindow.java:822) zombie.GameWindow.mainThreadStep(GameWindow.java:579) zombie.MainThread.mainLoop(MainThread.java:69) java.base/java.lang.Thread.run(Unknown Source) This exception then repeated on consecutive frames. So the fresh vanilla run ended up with: animal relationship corruption strange fence-bashing behavior suspicious trough behavior and later a render-state crash when returning to base Why I am reporting this together I do not know whether all of these are one single bug or several separate bugs. However, they all happened in the same fresh vanilla singleplayer run with no mods and default sandbox settings, so I think it is important to mention the full context. The most serious/clearest bug from my point of view is the cross-species parent-child relationship corruption: ewe linked to Leghorn chick chick following ewe as if it were its mother That definitely does not look like intended behavior. The renderer crash may or may not be directly related, but it happened in the same save after these animal issues had already appeared.

One shouldn't be able to remove batteries from devices in which they have no means of unscrewing the backing from.  Upon starting a new game, I watching my survivor whip out a screwdriver and unscrew the back of a Radio. I didn't know I picked up a screwdriver, went looking through my very limited inventory, and discovered my survivor whipped out a non-existent screwdriver to get at the batteries. Where did it come from, Where did it go?  Because this irked my immersion bug... You have now just 'lost the game' - you're welcome.

Well said @dgh, i agree with your points both about the inventory and the guns topic.

I tried this method today. And while I was playing, I haven't seen any crashes or errors so far. Thank you very much! 🙏

no-no, you didnt get a point. My character couldnt get wet AT ALL. Not even sweating. I could put him in 50 degree celsius car and dude tanked without a single drop of sweat
