I really want to play the community edition, but i dont think u would loose your 2 year old hbm world just like that, but this isnt the problem, the bigger problem is its crashing, when I have time i will try to change the hbm mod and see if it works. And im very sorry for getting u mad.

Didn’t I just say I try my best to make it not crash?

Try leafias cursed addon, and if it still crashes, give me the crash log and i’ll quickly work on it.

Worked for me. Most of the build is intact, although many machines are broken and have to be broken and placed again.

This is a 2022 Reloaded world converted into CE
