Merchant Tab bugged

So i just noticed one of my tabs was not letting me put any items on it (like a remove-only tab)



Bug Report ID: #507.338.284

Has been bug reported many times, the main workaround I've found is after at least 5-10 minutes (long after you read this message), it will start working after as long as you have re-instanced.

Several theories not worth getting into, happens a lot depending on how many items you sell, only the one tab is locked out temporarily, and will recover itself after the above time + re-instance is fulfilled.
