The mod Ammo Loader+ (1.1.2) caused a non-recoverable error.
Please report this error to the mod author.

crashed directly after creating a new game.

Mods: Space Exploration, Krastorio 2 and more

If you start a new game without this mod, save, and then turn it on and load the record, then everything works.

This error doesn't require Space exploration or Krastorio 2, I reported it 3 weeks ago.

Wow guys, really sorry I let such a game breaking bug go unfixed this past month. here I thought I had everything pretty stable.

I'll include a fix for this in the next update, which I'm currently working on. I'll let you know here when I've got something uploaded

I just uploaded 1.1.3 which should fix this bug. Let me know if you still have issues!
