Hello players and staffs, As the topic describes, the main issues with client crash primarily happen during Bossing, PQing (especially in APQ, keep crashing drives players crazy) and Leeching (sometimes happen when multi-clients). The crash issues have no difference between single-client or multi-client. Since Valentine's events have been ended, the client crash issues were starting happening until now I am getting mad. I have been always disconnected from APQ, 4 runs were cut into 2 runs and got 2 Onyx Apples making me pissed off more. After I re-installed the client, the issues temporarily seemed to become somehow stable. However, I will never be 100% certain the client crash issues will never happen again. Please check if the background scripts are making some issues or just update the client.
