I've searched through both the civilopedia and the bug summaries for FfH and FF...but no mention of this. Ancient Forests seem to be more than doubling my build times with workers.
3 workers, all with skilled I II and III (110 work rate) building a mine on a forested hill takes 10 turns. The same 3 workers take 22 turns to build a mine on an ancient forest hill.
Cottage turn builds have gone up to 22 turns from 6 on the AF tiles.
I've reloaded the game hoping it was some weird bug, but it persists through the save and the restart.
