If you have any time today we would appreciate you trying out the Steam Marketplace on the Test Server. Right now, the only thing available is the ability to trade your items with other players. No sale transactions will take place.
Your account items on the Test Server are separate from you account items on the Live Server so don't worry about losing them in the main game. The point of this test is to try and break the system. If you do encounter a glitch of some kind, post it in the comments below with detailed steps of what you were doing that lead up to the issue.
You will need to run around in the game for a few minutes before your account items will show up as available to trade. Steam inventory only updates when you start or exit H1Z1, or when you perform a trade. Right now if you open a crate, then the steam inventory will be visually out of sync until the next time you start, exit, or do a trade.
This is a known issue so no need to report it below.
Thanks in advance for your help and reports!
