uuu, that's a big issue. Will need some redesign of certain things. Thanks for reporting.

wrote a little app for it. Turned out with warping nether unloaded one tick shorter. Might have to do with server tasks. But with tick rate - shouldn't be an issue. Maybe its lag related (this 1 tick difference) since warping pretends to a constant lag for the server.

Can you confirm its one tick difference, or something else.

"tick freeze" breaks mob switch

but the issue of "tick rate" is 1 tick difference. I thought that was the same issue as "tick freeze" one, sorry about that.
