• Did you tried to disabling some mixins in the mod config to see what mixin made the issue?
• Did you find what mixin made the issue?

Description

As soon as I build the portal and log into the Nether or the End, the blocks of their terrain aren't loading. All I can see are mobs, and I can't move there (unless I use /tp).
I have FalsePatternLib v1.0.1, UniMixins v0.1.17 and OptimizationsAndTweaks v1.13.9 installed, my Forge version is the most recent. I tried disabling all the mixins of OAT in its config file, and it didn't work. FalsePatternLib's config doesn't seem to have any features, that have any impact on the situation, so I didn't change anything there, but as soon as I delete it (or OAT), the problem is gone. Will be grateful for your help.
