Hey guys! Thanks for reading this ^^
I was just chatting to my friends when I decided to go do a few quests in the meantime. I quickly came to realise I couldn't talk to the trainer, or any other npc for that matter. I relogged, same problem. I restarted my computer, same problem.
Then I went onto another of my characters and found I could not recall (it would show the animation and say it in the combat log but nothing happened), I could freely walk among mobs standing strangely still and could not attack them. It was like my internet had lagged out completely but... it's just fine.
I have a freshly-downloaded copy of istaria, so hopefully there'll be an easy copy+paste fix, but I couldn't find anything by google or forum search.
Thanks for any replies! Hopefully this will be the last of my many istaria problems in the past few days haha :P
