im playing on 1.12.2 on forge 23.14.5.2860 and i have over 127 more mods im playing with, i started experiencing a bug after i created a mining dimention portal, if i saved and quit and rejoined a different world i would load in but if i created a mining dimention portal then saved and quit, if i tried reloading into the world i would crash every time.

ME too

I'm getting this too and it seems very easily reproducible. I'm not sure if this is a mod incompatibility or something but all you have to do to reproduce this is leave a world and try to rejoin the world then it will crash. List of mods should be in the latest.log file to help the mod developer reproduce this issue and try fix it if they want to do that.
