Hello,
Do you experience this issue in any other aspects of the game?
What version of the mini client are you using?
Have you recently cleared your cache and flushed DNS?
Please let me know, thanks!

Have you tried this or experienced this with an older version of the miniclient?

Alright, we haven't been able to find anyone else experiencing this identical issue with an actually crashing PC, so it's probably some combination of incompatible hardware unique to your situation. The fact that it's happening to you on multiple computers is extremely strange. You didn't download your miniclient from one of those sketchy sites *not* offered by us, right? You got it from our official site, right?

That not being the case, I would suggest at this point that you suggest putting in a ticket with the customer support team to see if they can find out if something is causing the crashes with your account. It might be server-side, and there could be logs of it. Here's the link to do so.

And please let us know if you have any further updates.
