Geysers can infinitely push you up into the sky past its limit, One of the ways I found to recreate it was going afk on top of the geyser.

I'm unsure why this was a closed issue, but I came here looking to find a solution to this exact issue. Thankfully I did find out that through commands if you give yourself levitation it will overwrite the infinite geyser levitation.

Also experience this. Thanks for the comment, but it should still have been fixed and not closed prematurely

I really thought I had fixed it, as I took every measure possible to make it stop after reaching a certain height.
The problem is: I can't reproduce it, no matter what I try. I'm not sure if it's an incompatibility with another mod, and I really don't know why the code to prevent this is not working.
Does this issue also occur on the 1.19.4 version?

Hello, I was just playing on my survival world when I looked away from my monitor for like a second and then I looked back to see myself just floating up. This caused me a great deal of confusion and amusement, and, thankfully, I was able to clip it.
MC version is quilt 1.20.1, mod version is 1.7.1.

Oh and the best thing is: I looked away at my second monitor to watch a video about an aviation accident.

This bug still persists in 1.21 and has happened to me twice :D it seems to me that if the game freezes for even a second when entering a geysir, the levitation will persist indefinitely.
