Thunderstorms in Snowy Taiga, Taiga, Giant Tree Taiga and their variants are causing extreme TPS drops

I was in Snowy Taiga buffet trying to survive. Suddenly, a thunderstorm started and everything became slower and slower till mobs almost didn't move at all. No FPS drops, just slow mobs.

Other snowy biomes are okay, just Snowy Taiga and its variants are laggy

This is caused by foxes pathfinding to 0, 0, which is described at MC-179916

Best way to reproduce is to create a single biome (buffet) world with one of these biomes.

We do not have enough information to find the cause of this issue.

While the lag occurs, please run /debug start, wait a while and then run /debug stop in order to create a debug profile. Afterwards, run /debug report.

If you do not have the permission to run these commands, open your world to LAN and enable cheats. If you're on a server, make sure that you're a server operator in order to execute these commands.

Then, please attach the profile results found in [minecraft/debug/profile-results-<DATE>.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder], as well as the debug report found in [minecraft/debug/debug-report-<DATE>.zip|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder] here.

Is this still an issue in 1.15.2?

Yes, it is. My old account broke and I had to create a new one. Normally, I would add 1.15.2 to ''Affects Versions''.

Changed that ticket to your new account.

But I have already posted this. Do you want another one?

This is only the profiling report.

Can reproduce in 1.17

Is this still an issue in 1.18?

I think this is potentially duplicate of MC-179916, because I dont see TPS drops if there are no foxes. But I can confirm MC-179916 in 21w44a
