hmm, all my saves seemed to be or get bugged in this game, it seems like the state doesn't change for some quests like Heather's money problems i wonder if it has something to do with the time frame. I tried doing it incrementally and tested with before and after blue flower quest clear, cant seem to clear it. And I've also encountered the invisible or missing cat bug on my new play through. I like the implementation of master's but i don't like that it you are able to re prompt the master speech it should be done after first talk and then gone for ever, but i assume it not fully implemented, i managed to get Redd to give stone path and it never showed up as a recipe and after that it bugged as well.
Seems like the copper hammer is still bugged so i "respawned" the old one. Had various crashes after upgrading all gear to gold except for hammer just kept it at stock, would advice people here to do the same, since it seems to crash your game more often and only upgrade everything else up to iron after that i would be careful to recommend anything else than the pickaxe.
Seems to me that many of the bugs that were before keep crawling back. There is probably a proper way to play through this game, but i would wait for a proper guide.
TLDR: The same bugs that i experienced in R13 is still here, dont upgrade the hammer it might break the game. Iron seems to be the limit for most upgrades except pickaxe. still didnt get derek too acknowledge my awesome golden pickaxe. Some new scenes, but imo not worth the grind atm.
