The only things "working" to fix the issues so far are :
- disconnect/reconnect
- wait a certain amount of time (dozens of seconds at least) and **sometimes** "everything works" again properly
Stay strong and keep pushing forward. Just mentioning this (concurrent programming?) bugs in the general chat on experimental official servers caused quite a stir, showing how challenging and significant this issue is. Your persistence and determination in tackling this major issues are truly appreciated. Remember, every bug you fix brings the game closer to perfection. You've got this !
After client crashes, for me, it's the major issue. (just my opinion)
And I'd like to point out that, like most players I encounter, I experience far more client crashes compared to the previous experimental version.
