I was running the mod pack “Better MC 1.16.5” and I removed roadrunner since it's not compatible. The server ran great for 8 hours, however after rebooting the server I have received this issue.

I am unsure how this has happened, and any feedback would be appreciated.
Thank you for your time!

Try to delete krypton reforged, and retry

And i have a question ,where you found jmt_mcmt 0.23.89-PRE

on curseforge the latest is 22.87 in 1.16.5

It's in the discord, dev artifacts. And I'll remove krypton reforged and let you know how it goes.

I have deleted Krypton and no success in the server starting, I noticed this in the crash report which is kinda odd.
"Exception message: java.lang.NullPointerException: Registry Object not present: cavesandcliffs:axolotl_attackables"
^ I see this now, which is weird to me.

(P.S Dominic200527 is my GitHub on my phone)

you tried mcmt 1.16.5 stable version from curseforge

Yes, I have used the stable version from curseforge. Thought of trying the pre version as a last resort to it.

I have the same issue with
"Exception message: java.lang.NullPointerException: Registry Object not present: cavesandcliffs:axolotl_attackables"
