It has come to my attention that the mini client and perhaps the game itself has a massive memory leak issue.
I realized this earlier, and confirmed it just now. Where the game first crashed on me, and then slowed my computer to a crawl.
After opening task manager and closing any applications including the game itself which was frozen at this point I realized that I had over 4 GIGAbytes (GB) of active physical memory.
Seeing as I did not have League of legends and heroes of the storm on at the same time, I can only assume that those GBs of active data were * data, leaked out by the game.
A restart fixed it of course... but the damage has been done. Not only was my computer threatened with a bluescreen, but I also was crashed while conveniently participating in the Sage World Tournaments.... a minor inconvenience, yes, but it still causes me great annoyance.
I really, really hope this issue is resolved...
