Yesterday's 6.11.2019 patch brought a series of client performance issues caused by a memory leak (abnormally amount of client memory usage), which leads to low frames per second in-game, and client crashes. We have already deployed a patch attempting to fix those issues which has proven to be partially effective, and we're about to deploy another in a few more hours attempting to completely fix those issues. We apologize for the inconvenience and negative experience we have caused by this recent update, thank you for your understanding and patience as always.
