Well, I do have the same problem. This morning I had to reboot the computer. Didn’t work tonight. The Bazaar stuff I bought do work in solo mode… but not when I play on a server.
Other bug that is probably related, at one point, I had access to the new yamatai pieces, but when I tried to put one down, it was telling me I was missing parts … But all the parts were in green and were in my inventory … I don’t have any problem with any other pieces from the " base content ". I tried Killing myself, and then the bazaar content was yet again unavailable… I do wait a bit as LAG might be a problem, but after 10 minutes, I don’t think lag applies.
