Trophies I didn't take?

That is caused by fixing another bug that prevented the "NPC trophy hoarding" mechanic from working. NPCs hoard trophies, and whoever defeats them gets them. Because it did not work properly they managed to hoard a lot more trophies than they should, and they only hoarded cosmetic trophies. So when someone beats them the first time now they got all of that.

It should balance out after that, and they should also be taking functional trophies as well. You should also be able to sell stuff you dont need at the Shop now. Or soon with the coming updates.

Ooooohhh! Ok. Gotcha. Forgot that became a thing.
