[41.65][Multiplayer][Server] NullPointerException zombie.iso.IsoGridSquare.getX()

[Davelantor]

• 41.65
• No mods
• Does not crash, but Exception happens each tick, causes cars to not function, admin car spawn option does work, VHS tapes dont play, cant break down barricades etc.
• Server Brutality [ENG], server has been running for 3 weeks with no wipes, restarting the server seems to fix the issue.

We have weekly maintenance windows where we restart. Things get funky when the server is running for more then 144 hours at a time. So for us we decided to just manually restart the server in the off hours. Takes about 15-10 min to get backup with a heavily modded codebase. Seems to be the best solution for now!
