Checklist
- I am using the official version of the mod.
- I tried the latest development version but the issue persists.
- I searched for similar open issues and could not find an existing bug report on this.
Try reproduce without carpet-fixes.
@ishland you are right. It works fine with carpet-fixes disabled.
carpet-fixes.conf:
optimizedHypot true
optimizedRounding true
optimizedPoweredRails true
optimizedTicketManager true
optimizedBiomeAccess true
optimizedNeighborUpdater true
optimizedRecipeManager true
I would suspect optimizedTicketManager as it caused a similar crash before.
Disabling optimizedTicketManager fixes the issue, indeed.
What would you suggest optimization-wise is better VMP or carpet-fixes with optimizedTicketManager? My server doesn't have that Many Players. Is there any benefit in running VPM on low player (<7) servers at all?
VMP contains a better version of optimizedTicketManager along with many other micro-optimizations. It will still reduce mspt slightly on entity-heavy scenarios on lower playercounts.

https://pastebin.com/b8uZT2mE - List of Mods
I've been having consistent crashes with VMP, I have no clear idea as to what's causing it, but in terms of the stuff above, I do have a similar mod called "Debugify" which implements some fixes
After doing some testing, I have experienced no crashes so far with VMP disabled,
@Poke097 Please try getting the minimum list of mods reproducible and open a new issue.
Closing as resolved.
