I can provide the save file, but it's quite a few mods.

Same error, I had to revert to 1.1.32. I am playing Krastorio 2 mod, open a chest with Uranium-238 in it and it crashed with the following error:

5562.669 Error MainLoop.cpp:1391: Exception at tick 15337003: The mod Ammo Loader+ (1.1.33) caused a non-recoverable error.
Please report this error to the mod author.

Thanks for letting me know! I just uploaded 1.1.34 which should fix this issue.

Let me know if you still have problems after updating!

Just tested with 1.1.35 is now working well. Thanks for the fix & your hard work on the mod!
