[LP] Weird bug - all civics suddenly takes 1 turn

[kaspergm]

Never experienced this issue before, but at some point during ancient era, suddenly all civics take 1 turn to finish. I thought at first this was some sort of culture overflow due to Ramses unique ability, but it persists now through 15 turns where I get a civic each turn, so clearly some bug is at hand, possibly a mod conflict. Have anybody ever experience this issue?

It could still be overflow, this persists, but how you managed to get such a huge overflow is another question.
