A-sync trade/Market tab locked from AFK player

Someone joined my hideout via a-sync trade. Then proceeded to AFK for 30+ minutes, which locked me out of my market tabs entirely. They didn't buy anything. They never moved. I couldn't click on them to report them directly.

I didn't think to note their name before swapping my hideout to force the instance to close. If it's able to be analyzed, this happened at around 2AM CST.

1. There needs to be a way to view players in your hideout and the ability to remove them from it.
2. The market tabs were locked the entire time, this needs to be a time limit of no more than 120 seconds before it unlocks, not until they buy and/or leave.
