Thanks for the insight.

I had figured out that it was related to the scenario map, since loading the mod on a 'normal' map did not break the code.

Yeah, the error did not occur in 1.1.x, I used the mod/scenario multiple times there. Hopefully I will be able to load the scenario in 1.1.x and fix ...

I'm trying to load the game with a mod I created in version 1.1.

The "Base mod [2.0.39]" and "Factorio Bingo [1.5.0]" is loaded as the only 2 mods

I press Single Player -> New game -> Mod scenarios -> Factorio Bingo/Factorio Bingo -> Play
- Loading new map progress bar appears ...
