Ok, a series of weird events have been happening tonight, and I couldn’t resist to write about them 
• I was repairing some stuff on my druid. I was switching between sets, caster and melee. I completely forgot I had the vendor dialog up when I started to switch items, so I sold two pieces of my melee set T_T
• I was going to BRD to help someone with a Barman Shanker run, as my main… took me a while to get there, and when I was about to open the lock, I noticed I didn’t have the key.
• I went back to Ironforge to get the key off the Bank, when I land in Thorium Point, I hear some noises and notice that I got Mind Controlled. I was thinking that the horde was going to send me kill the Flight Path Master, a few of them dance with me, and I get released, then I hear some noise as if they were going to begin casting, and I could vanish and sprint… hahaha, I really can’t believe I escaped T_T
• Then, in one of the resets, we see a horde rogue. We were about to pwn him (we were three rogues), and he vanishes. For some reason I see him “behind” the instance portal, he just sat there and began to eat… then I began shooting my crossbow.. hahaha, he got pwned by it…
• At the end, in one of the resets we were going in and I get disconnected right in the middle of a bunch of mobs… When I get back, I could barely vanish… hahaha, I was really scared of dying T_T
Hahahahah
Wow did you contact a GM to get your set pieces back? I know people who have sold multiple items to a vendor and was able to get them returned.
One person in MC was reapairing at a bot and sold all his armor to it
Well, it wasn’t even a “set” item, just a quest reward. I did contact a GM about it and he explained me that every account has a limited number of times in which users can recover items on such situations. I changed my mind at the end and decided not to recover.
