CAN ITEMS GET EATEN?

So I'm midway through playtesting my game and I've suddenly inexplicably lost my tent item (it's a unique item). My game has a few items, and I'm wondering if it's something like too many items in the inventory and the ones that crowd the storage out get lost.

That, or I've gotta test through to make sure no code has it accidentally lost. Nvm, I think I figured it out. But is there some upper limit to the variety of items that party can have? And what happens if you have new items if there is?
