Hello. Since I updated the mods yesterday, it keeps crashing when I load my save game. I don't know which ones exactly, several have been updated. I tried trial and error to determine which one is causing the problem, but unfortunately to no avail.
Please, can you help me? I don't want to play Factorio without ammo loader because your mod is really great.

My error report:

Die Mod Ammo Loader+ (2.0.4) hat einen Fehler verursacht, der nicht behoben werden kann.
Bitte informiere den Autor der Mod über diesen Fehler.

Error while running event ammo-loader::on_tick (ID 0)
LuaItemStack API call when LuaItemStack was invalid for read.

me too

same here

I think I figured it out.
I had coal and wood in a burner, when I deleted or upgraded it, crash.
I think the code cant handle mixed fuel types.

I just released version 2.0.5 which should fix this issue. Let me know if you still have issues after updating!

Works again without any problems. Thanks a huge lot for fixing it.
