After updating the game to version 0.18.43, it gave me an error at startup:
24.176 Mods to disable:Failed to load mods: File not found: base/graphics/technology/effectivity-module.png
Mods to be disabled:
• boblibrary (0.18.10)
• CircuitProcessing (0.3.4)
• bobmodules (0.18.5)
• angelsbioprocessing (0.7.13)
I think the problem is in bobmodules.lua at line 60:
data.raw.technology[s.."-module"..i].icon = "base/graphics/technology/"..s.."-module.png"
If I change that to:
data.raw.technology[s.."-module"..i].icon = "base/graphics/technology/"..s.."-module-1.png"
Then it works again.
