Had issues in HoH yesterady too. Was fighting an earth trash tree and at 56%, everything just stopped on all my toons. Zone didn't crash but my toons just stopped fighting. Environment stayed moving and a guildy was in zone fighting and his was fine. WinEQ2, MQ2 basic here as well.
I said something in guild chat and I could see what I said but not replys from guildies, but when I went to my other computer and looked at my chanter buff bot, the chat from the messed up toon was still going to guild chat. Was just all around weird. lol
Lost sync between your client and the server. Happens a lot actually.
I just roll with the punchs when that happens, it usually means I get a free gate to rebuff myself
