So I was on Grizzleheim doing some combat until I get this "error occurred" notice and my game shut down randomly. I tried relaunching the game three times, same thing. So then I decide to switch over to my PC, and it's the same thing! I don't know what's happening, but I hope this doesn't prevent me from playing w101 forever.
The exact same thing happened to me a few days ago! Was on laptop, in a battle, game crashed/laptop turned off, switched to pc, still crashing. I'm able to go on my wizard now because I guess the game had finally decided that my wizard was in the fight for too long dead, and sent me to the commons area after about 30 minutes since initial crash. I think your wizard is ok to go on now. I wonder how many others have experienced this random crashing?? It makes me worried that it'll happen again when I'm in some other important fight. The new wysteria lore spells are apparently a cause for the crashing (not sure if they fixed that yet), so if you or anyone fighting with you casted one of them, then that's probably your solution. However, that wasn't my case and I'm still trying to think of a trigger for my own scenario..
