I think this bug is related to this mod but not s ure

[az201601]

I recently installed this mod... everything worked fine.. except that sometimes blocks will randomly become another block... water becoming emerald ore, skeleton skull etc... dirt becoming dead bush, grass blocks turning into moss stone... wasnt having this issue before i installed this mod.. so im assuming thats the issue of this mod..

Can you provide logs and such?
Are you using things like NEID or EndlessIDs?
What generator are you using?
Does it fix itself if you disconnect/reconnect.

This seems like a block ID issue somehow so not sure why our mod would cause it.
