It has been a while since I played Keyflower here. I don't remember it as being too buggy, but the game I just played contained two major bugs with upgrading, where it failed to consume a resource for upgrading a tile (but did the upgrade anyway). Is this a recent problem?
A developer contacted us to fix a bug end of August https://boardgamearena.com/bug?id=4447
This may be a regression due to this fix. I asked him to review this post but got no answer.
For now, I reverted to the previous version, please let me know if it makes it better.
only played one game but didn't see the same bugs. also the mobile use seemed to work much better...clicking on a tile actually brought up the workers to place on it, which only worked like 20% of the time before the rollback.
