Can confirm this issue is still present in 1.21.1.

Can confirm this issue is still present in 1.21.1.

You mean 1.20.1?

Brief Update: Turning the doTraderSpawning gamerule to false may be a bandaid fix for 1.19.2 for now.

im having the same issue, I encountered yet again, another alex mobs elephant issue: [01:13:58] [Worker-Main-7/ERROR]: Async chunk load took way too long, this needs to be reported to the appropriate mod.

[01:14:40] [ModernFix integrated server watchdog/ERROR]: Thread Dump:

My previous report Elephant Nukes the Server 1.19.2 #1803 was closed, which means either there was an updated mod file posted somewhere or the issue was not resolved, the best way to reproduce this issue is to just keep Tp around the world, I do it in intervals of 10000 each, eventually you will not load anymore chunks and it will freeze, OR, what happened in my case was I was searching for a biome in chunks that were loading fine, and then it froze after searching, so even looking up biomes causes it to crash on 1.19.2
