Shop Bugs
The first bug is with Perfect Timing's stopwatch, when you sell it, you get the full amount of gold for a split second, and then your gold is reduced to make up the amount they intend for PT's stopwatch to sell for
This is kind of frustrating because the game will highlight things you could have bought with the full sell value of stopwatch, when you can't actually buy them with the amount of gold you have
Second bug is with biscuits. If you have all 6 slots in your inventory full (say I have broken stopwatch, frostfang, control ward, boots, and 2 mana regen charms) and I back and complete an item with 2 components, (say I upgrade the 2 charms to forbidden idol) I get a biscuit in the free slot. That's good, but I can't then undo my purchase and instead sell the broken stopwatch and buy Aether Wisp if I think that's a better idea
A biscuit going in your inventory removes the ability to undo your purchase, which really shouldn't be the case imo
