Hey there,
Thanks for keeping this mod going, love these little guys myself, and I prefer them over any of the other alternatives for early game!
I've got an ongoing game with Krastorio2 and several other mods, and I got a loading issue after upgrading from 1.0.4 -> 1.0.5... rollbacking to 1.0.4 solved the issue for me, but I wanted to report in case it's something that needs to be taken a look at.
The error given by the game taken from the factorio-current.log is this one (only a single line appears to be logged):
113.541 Error AtlasSystem.cpp:1543: File not found: Updated_Construction_Drones/data/tf_util/empty-sprite.png; mods: Krastorio2 aai-industry FluidMustFlow Transport_Drones Updated_Construction_Drones
Not sure is that's something that conflicts in some way with the mods listed? When loading after the game loads all mods, it fails to continue presenting the usual window when an issue crops up and the only way to proceed would be to disable the mod and reload.
If you need the whole log, I'll keep a backup copy in a safe place, so I can post it... but other than that line, it hasn't anything else related to the error.
