I'm having repeated issues with chunkloading on this server (1.20.1, forge 47.4.10), every hour or so as we just started this world and we're exploring. Hosted in online mode on my pc, with 16 GB of ram allocated. There were 4 players on at this instance but it happens when I'm on alone, too. I've never had an issue like this hosting a modded server before.

This is a modpack we just cobbled together via prism client and have done some minor config edits for. We've parsed down the modlist and done other world testing, taking in and out groups of mods but unable to replicate it exactly.

My Java is Eclipse Adoptium jdk-17.0.18.8

I've resistalled the server, reinstalled java, taken mods out one by one, and refreshing the config. I still get the error. I'm using chunky to find the corrupted chunks faster. After removing alex's caves, artifacts, traveloptics, tectonic, biomes we've gone/trees you'll grow, fossils and archaeology, pehkui and all of FTB suite, I'm still erroring. Using chunky to preload (was not previously installed). Second crash report from just now, no Chunky.

I already had this posted to a gist to show someone else so here's that, sorry its not pastebin

i just realized how undescriptive my title is, it's a NaturalSpawner issue, I think.
