I know that it has been mentioned before in the fqa but my situation is different.
Context:
Made a bedrock world and recently converted it to a java world.
Before trying to add any mods, I loaded it on official mc luncher with no issues. Then to prisim with performance enhancements and saw that it worked fine.
After I made a separate world within the same instance to add dh amongst others to see of they are compat able with each other. They worked fine.
So now thats clearex up, I then used all those mods and loaded in my old world and I kept getting error messages from dh only, causing my game to crash.
Reloaded with only dh and same thing. Errors and crashes. Not sure if this is because its was a bedrock world that was converted to java or not.
