I just started up a new run with my usual 200+ mods and got this message about this mod:
Failed to load mods: Error in assignID: quality with name 'uncommon' does not exist.
Source: inserter-capacity-bonus-2 (technology).
Does that look like something caused by this mod, or might something else be triggering it. If the latter, can you give me a clue as to which mods to investigate? (I can paste the contents of 'mod-list.json', if that would help.)
