I was doing mirror lake killed tse-tse snaketail then moved on to next battle, I defeated the bosses with glowbug squall and didn't get any drops not even gold! I looked In my backpack for any extra items but there were none! I moved on thinking it wouldn't happen again but it did In the next battle. I don't know whats going on but please fix this because I like getting neat armor by farming these bosses!
I find that you need backpack to not be full and also make sure you dont have 999 of any reagents. Idk why That sometimes can affect the drops. Its weird. make sure you dont have 999 of reagents or pet snacks. After that It should fix itself.
