lots of "[Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 7674ms behind, skipping 153 tick(s)" and "[Server thread/ERROR]: Failed to save chunk"
there is no such thing as " .minecraft/crash-reports/" , only "\.minecraft\logs", so i attached logs from there.
as for you , ethan, keep your "it didnt happen to me so its not real" bullshit shitposting off my bug report.
i've just added all the logs, as there are, from the past 2 days, as It crashed yesterday and today, but so far I haven't been able to duplicate the crash.
