when attempting to load chunks near or at a pillager outpost, completely kills chunkloading and crashes server

Reproduction Steps

1. host a server and join it
2. locate a pillager outpost (for me it i just tried to locate frozen peaks)
3. sit there in confusion as your server crashes and floods your console with "Empty or non-existent pool: minecraft:witch_hut/foundation"

This is caused by Dungeons and Taverns, which isn’t in v26. I would recommend reinstalling a fresh version of the server pack and transferring over only your world folder. My mistake, wrong modpack, but try removing Dungeons and Taverns.

Hello, i have the same problem here, removing Dungeons and Taverns solved the bug? Any alternative to keep the mod ?

[AstroLive0]

It does kind of solve the issue, there isnt really an alternative right now but ive asked the mod developer to fix the issue for 1.20.1, as they have fixed it for 1.20.4 edit: the mod developer will not patch it for 1.20.1 (fair enough) best bet is to keep it removed until better mc is optimized for 1.20.4 at the end of the day i would recommend some other mod pack (at least for forge) or to just make your own mod pack as i have had to spend hours deleting bloat mods on the sever pack and fixing compatibility issues that are causing massive memory leaks and extreme TPS loss. (also update all your mods on the pack as a lot of them have serious memory leaks, just make sure to only update them to 1.20.1) i went from a fluctuating 13tps on a ryzen eypc w 128GB RAM, to a stable 20 after fixing the issues.

Thanks you for the advices, i will try to update all mods from server. Btw, how do you check your TPS ?

[AstroLive0]

I use Spark Profiler, which comes with the server pack; run /spark profiler start wait how ever much time you would like and then run /spark profiler stop what ive been doing is starting it, playing the server w my friends and then after around 15 minutes i stop the profiler, it will output with a link you can go to which will tell you a lot of stats including RAM usage, CPU usage, TPS, and things like which mods are taking up the ticks (fyi if it says neruina is taking up a lot, ignore this as thats just how the mod works, it isnt actually taking up anything)

Ok il will check that, thanks you ! 😊
