Waterfall smoke particles continue summoning over and over again without despawning, and fall through the world into the void.
Seems to happen far away, around the edge of the view distance.

I'm experiencing the exact same thing. Performance is taking a massive hit and dropping me from 120 fps to 12 fps when particles don't despawn.

Still happening with latest version.

It appears to be related to the config file, changing settings on the config can trigger this.

Are you able to find a specific config that'd cause the crash, and send it? It's fine if no, but I need somewhere to start w/ debugging this

Alright well since this isn't getting addressed I can't recommend this to anyone, and I will actively advise people not to use this.

I will do my best to investigate, sorry for the delay.

@jacklollz2 I've been unable to replicate the issue after ~2 hours of debugging on version 1.6, are you able to provide a world/specific case I can use to somewhat reliably replicate the problem?
