Describe the bug you're experiencing

With this mod installed, tick times while generating chunks skyrocket to several minutes each. I opened the client up in IDEA's debugger, and all of the time is being spent in chunk generation. Nothing weird in the callstack (except that only one worker thread was active, now that I think about it), it's just the chunk generation taking forever even for vanilla biomes. The issue vanishes immediately after uninstalling the mod.

Reproducability

Use this modpack:
epochS2.zip

Load a new world with default settings, and attempt to generate chunks. The tick loop should freeze as the server thread blocks to wait for the chunk generation.

[will do, just saving issue first]

can't reproduce it, probably not enough ram assigned and you did not use the up to date version (4.5)
