Merchant tab stopped accepting itens to sell

Bug Report ID: #4.125.326.688

I have a "maps" merchant tab that stopped accepting itens to sell. It is populated with maps that i can only remove, but when i try to add a new item the square is red and doesn't accept the item. I can put itens on any other tab but this one which was working fine yesterday.

Maps tab (with he issue; red square):


Another tab (no issue; green square)

+1

Can't place ANY items into Merchant tab to sell. Everything was working as normal few hours ago but as I logged in, can't sell anything anymore.


Edit: Tab started working again, wasn't fixed by logging back in again but by running a single instance.

Went back to normal for me too after i logged off for a while.
