95% yes. I logged in after the latest DLC and found out that my henchmen trinket had been deleted. Since there is 0% that someone hacked my game account solely to delete ONE item and do absolutely nothing, I think it is safe to say that even our inventory is glitching.
Really sorry to read that. Hopefully I'll get restored along with anything else that's missing. I wonder how DCUO devs are going to respond to this? Too late to blow it all up now! I'm right there with ya.
