Factorio Forums

Although I haven't seen this problem personally, I've seen quite a few reports in my mod section of my mod being Redded out. After further investigation it was caused by a Base mod >= 0.12.0 check fail, due to base mod not being loaded, or checked properly.

Details in my forum. https://forums.factorio.com/forum/vie ... 436#p98085

I guess, that it might be possible result of other bug I just fixed:

Fixed that non-default mods were not loaded during the first start of Factorio after mod-list.json was deleted.

It theoretically could happen, that as the mod is not loaded, the other mod that has it in it's pre-requisition might not load as well and disable itself.

If that is the case, it is fixed for the next release.
