After updating to version 0.2.13, I'm getting an error when opening the "fluid mining drills" module, while version 0.2.12 works normally.

I can't find the mod "fluid mining drills". Did you mean "Filter Mining Drills"? I specifically tested with that mod.

Seems like I messed up the commits. Will be fixed in the next version.
