Sable hard crashing the JVM

[devprinter]

Context

The log file ended abruptly and there was no crash report. The only evidence of this happening was in stdout of the server

Apparently this has been happening semi regularly, about once per day

I am using a slightly outdated version of sable, but I'm posting it anyway in case you guys didn't know about it and it's still present using the current version. Haven't had a chance to update yet

create versions:
sable-neoforge-1.21.1-1.0.6.jar
create-aeronautics-bundled-1.21.1-1.0.3.jar
create-1.21.1-6.0.9.jar
