Can the issue be reproduced?
Yes

Logs
See referenced issue for log examples; mine were similar. Deleted my 1.65 instance already so don't have the log at hand anymore.

Issue
After updating from 1.64d to 1.65, our server won't start anymore and throws a ticking world exception caused by java.lang.NoSuchFieldException: delegate in Advanced Rocketry. There has been an issue created at the official repo (Advanced-Rocketry/AdvancedRocketry#1611).

Status at the AR repo is still "Unconfirmed Bug". No known workaround found so far.

Status has been updated to "bug" by the mod author.

Might be worth noting that we've had players go to space already. I would not be surprised if this issue doesn't show when that's not the case.

Perfect, thanks.

Fixed and released in new version. I'll check with a local install if it resolves the issue in E2E.

After updating Advanced Rocketry from AdvancedRocketry 1.12.2-1.6.0-149-UNSTABLE to AdvancedRocketry 1.12.2-1.6.0-150-UNSTABLE the server on 1.65 does start as expected without this issue.

At a glance our server does what it's supposed to do. If there are issues they are 1.65 issues and unrelated to this AR patch.

@NillerMedDild I think this can be patched/hotfixed.
