Inventory is full (isn't) when try to purchase Wizard Vault Items

[luigiormario.7305]

Hi, 

I am finding, after having purchased several items from the wizard's vault, that no more can be purchased with the error 'Your inventory is full'. This is despite at the time of purchase having over 100 free slots in my inventory.

I get the feeling they decided to stick the trade post spam sell message in the WV, juuust to slow us down even more lol.

Hmm might see strange to ask but is your mail full? This window, for the vault, it's blatantly obvious that it's a web page window just like the trading post is, and some of the trading post (the gem part) will send via mail, but it would potentially fail if the mailbox was full. We're not seeing things come in the mail like that but it doesn't mean it doesn't handle it like that on the game's backend.
