Description of the Bug:
I was unable to remove items in with the house decorator despite having sufficient item inventory space. This seems to have been due to my pixpet inventory being full, since the problem got solved after I placed some pixpets to free up space.

Steps to reproduce:
Have free item inventory slots but no free pixpet inventory slots > Try to remove item with house decorator.

What should have happened?
I should have been able to remove the item since there was enough space in the item inventory.

What did happen?
Wasn't able to remove item since my 'inventory was full' despite that not being the case.

My System:
Windows 10, Opera Browser (Latest version)

Since it's been a while, I don't remember exactly, but I think it was something like 'No inventory space'. I don't think 'pixpet' was included in the message.
If I manage to fill out my inventory again, I'll test it out.
