I'm in 1.19.2 (singleplayer) with v1.4.84 and, for some reason, every tick command works perfectly except /tick warp, every time I try use it it runs the game at normal speed. I tried for myself to understand the problem but I didn't find out (Every time I try to start a new warp and stop it after a few seconds, it says me it had completed the warp neither in 20 ticks) . Please can someone help me?

Sorry for the late reply, somehow missed this, it may be that the world is too complex for your computer and therefore it's not being able to warp, though it's weird that something like rate would work. I'd check if the game runs at the specified rate when changing tick rate just in case.

Given so much time has passed I'm going to close the issue, though if it's still an issue for you please open a new one!
