Game is consistently slow to start up my desktop computer (which has worked like a charm for years with the game.)
Often, the connection times out so the games never starts.
I see this error message:
HS:CT; NetCacheCardValue=1
or sometimes, the same message with =2 at the end.
I’m currently having the exact same issue. I even uninstalled and reinstalled Hearthstone and it did not fix the issue.
