Haha, you replied so fast; I was still editing my comment with more bugs! Thank you for catching bug 1 (music)
The boots bug also happens above ground, infrequently. I apologize for not mentioning that!
The furnace bug is definitely triggered with gold
Clay - Oooh, I see. I didn't realize that the update changed it; thank you =)
Bits and bobs/flares: yes, if the intent is not to have torches, then I understand, but this makes reaching the water impossible in vegan mode. Not only due to the lack of health, but also due to no flares/no torches making optimal restore cell pathfinding impossible (the strat for standard mode is to use one mageflare rune for every seven depth to get to water, esp with grampshell). Perhaps this needs rebalancing for vegan mode so it's hard but not impossible.
I mentioned a few more bugs in my comment above before I saw your reply; I hope you see those too!
Thank you so much for your fast reply!
