Alright, since this is a huge and difficult game, I figure most of the playerbase and interactions are still to be discussed and/or discovered. So, I have been wondering about generator fumes, specially now that we have multiple leveled buildings all over the place.   How, do fumes work? We all know they fill all indoor spaces in the same level as the generator, but how about levels above or below? Has anyone tried this? What happens if you place and connect a generator on a basement? or 2 levels above?   Mostly I ask out of curiostity and the need of clarification, but, also, I spent way to many resources clearing March Ridge and I'm too stubborn to just give up on the fallout shelter. 

Apparently the culprit was actually the rabbits who had multiplied beyond control. They were most likely thousands or hundreds of thousands spawning in at the same time. I managed to get here by teleporting just outside my house.

To add further information:   If I enter debug mode and choose to delete all animal population in the save, and then enter my zone, the game suffers from no lag or stuttering. So it most definitely have something to do with the animals in the base.

I have three chickens in my base, no rooster, as well as two sheep and two cows. When I approach the "zone" where my base is I drop to less than 1fps. If I hold the move keys to move outside of the zone again, the game resumes to working as intended. I suspect the chicken to be the culprit here due to another person reporting what seems to be an identical issue as what I'm having:   I've been stuttering/lagging too much to be able to approach my chickens, but I'm assuming it would look something like this. I'm even getting the exact same error messages as the person in this thread. This issue has already ruined two of my saves, as it's absolutely unplayable.   Logs are attached.   Thank you for looking into this! logs.zip

Version: [42.7.0] Mode: [Singleplayer/Multiplayer N/A] Server settings: [N/A] Mods: [None] Save: [New Save] Reproduction steps: 1. Start the game in (House in the woods - Last stand Accumulator) - edit 2. Generate some points to spend 4. Go to the weapon tab and purchase either 9mm rounds at a quantity of 5, or Shotgun shells at a quantity of 6   5. Receive a single bullet or shell. Seems pretty impossible to get past a certain point with melee with the new strain and fatigue combination, even sitting and popping pills between waves. Decided to try to gun my way through as well but this bug is currently preventing me from testing that out.
