I posted about 2 weeks ago, having trouble with my vendor disappearing. I chose OoTP on Tor Bazaar and he confirmed my order, but then disappeared with no response and me 280$ short (less now with the crash) but still. I have contacted support unanswered 3 times. I really do not know what to do.
Does OOTP vend on any other markets? You could try contacting him there.
