After selling an item through the sellback feature, the site doesn’t recount the amount of items in my inventory.
When my inventory was at 199/200 I sold five catnip seeds. I got the PC, and I had five less catnip seeds in my inventory. However, the number next to my inventory button still said 199/200. And when I went to collect items from hoards, I received an error message saying my inventory was full.

Other items I’ve tried selling that all had the same result:
x9 Bearberry seeds
x10 Giant clover seeds
x3 Green mushroom
x1 Aloevera seed

I’ve tried refreshing and even logging out. This is in Safari on IOS.

Thanks!

Definitely, they were even recorded in my PC history. Here is a screenshot for proof:

I got the PC but the game is acting like I still have those items, even though I don't physically have them in my inventory anymore after double checking. Those items are gone but the game still thought my inventory was full.

It does not. One thing I’ve noticed is that the sellback feature immediately counts off individual items, and stacks are what’s causing problems.

That’s fine, it might work itself out in the future or something. Thanks for helping though!
