Missing the second BF dungeon isn't a big deal (I skipped the BF dungeons entirely), unless you really don't want to miss anything.
Well in fact it's not really the bug that made me mention to start again the game from the begining but more because I learned nothing of objects interaction in Beyond but learned few stuff in Divine. So I realize that I didn't saw some points in Beyond, for example read that an item is important but not be able to pick it for later. Now I know that eventually drag and drop in my inventory will allow to pick it. Or be able to move an item could allow access something behind... Also not sure if there's telekinesis in Beyond but if it has this, I will take care to think about this possibility, and so on.
About BF I agree that this can be skipped, in my opinion that's not the best part of the game, moreover I never believed in random generation and BF is another proof for me that it's not a good way to go... On another way I am very curious and get quests and not be able to try them is a little disapointing.
