In my modded Minecraft 1.12.2 world, I’m experiencing cascading world generation lag, and Quark appears to be one of the causes. While populating chunks, Quark is loading adjacent chunks, which results in cascading worldgen lag and negatively affects performance.

[14:28:57] [Server thread/WARN] [FML]: Quark loaded a new chunk [-118, -79] in dimension 0 (overworld) while populating chunk [-119, -79], causing cascading worldgen lag.
[14:33:29] [Server thread/WARN] [FML]: Quark loaded a new chunk [-118, 125] in dimension 0 (overworld) while populating chunk [-118, 124], causing cascading worldgen lag.
[14:44:39] [Server thread/WARN] [FML]: Quark loaded a new chunk [-131, 149] in dimension 0 (overworld) while populating chunk [-130, 149], causing cascading worldgen lag.

This issue arises during terrain generation when new chunks are being loaded by Quark while adjacent chunks are still being populated.

Mods Involved:

Quark (contributing to cascading worldgen)
Other mods: LLibrary, Mowzie's Mobs, Open Terrain Generator, Biomes O' Plenty, etc., are also contributing to similar issues.
Steps to Reproduce:

Load a modded Minecraft 1.12.2 world with Quark enabled.
Explore new chunks and monitor the logs for cascading worldgen warnings.
Observe that Quark triggers new chunk generation while adjacent chunks are being populated.
