After filling worker chest with coal.

The mod Ammo Loader+ (2.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Was about to post up the same error glad im not alone on this one

Same on rockets, for example.

Error while running event ammo-loader::on_tick (ID 0)
ammo-loader/lib/Force.lua:869: attempt to index field 'bullet' (a nil value)

ammo-loader/lib/Force.lua:422: in function 'tickAll'
ammo-loader/lib/Handlers.lua:350: in function <ammo-loader/lib/Handlers.lua:333>

And on Artilery:

And same on railgun, same thing again:

ammo-loader/lib/Force.lua:869: attempt to index field 'bullet' (a nil value)
stack traceback:

I commented out line 869 in the file ammo-loader/lib/Force.lua and my problem kinda went away, maybe it will help

Yes, my friend did the same, if I understand him correctly, and it seems works

I just released version 2.0.2 that should fix this issue!
