Crash Report:

Modpack:

Vault Hunters 1.18 (alpha 0.0.3h, alpha 0.0.3)

Issue:
The server has been crashing after 4-5 minutes of starting up. I have also noticed that the RAM usage (2700MB) is above 95% within a minute of starting up.

The issue has been persistent for the last few days.
I've reinstalled a fresh new version of the modpack, but the issue is persistent.

bumping this thread, would love some help on this Julian

Has the 1.18 version of the modpack been removed from Aternos?

understood.
is it possible to still have the older version available to play? or does your system not allow for that to be possible?
