Upon finding this structure on the server it times out the server and crashes it.

I tried to reproduce the issue in singleplayer but couldnt do it consistently. It usually works in singleplayer but never in multiplayer.

Modpack: Benchmark II 1.18.1 0.6.4 newly generated world (With the oh biomes mod removed. )
Seed: 5924450926579097189
Location: 1294 77 -2720

Trying to go inside or loading the entire structure times the server out.
Configs changed from default: Server render distance changed to 15. All other options remain the same.

Crash report doesnt mention this mod specifically but yet here it is: https://pastebin.com/Aa2HmWFY

I'm also having the same issue, same modpack, on a server.
Seed: -6343544224602108497

Thanks this was fixed in 1.4.3!

Still crashing in 1.4.3
