I installed this mod on a server I made for a custom pack to play with friends and I noticed this mod gives you slow falling whenever you enter Spectator Mode. Well, yesterday I crashed while having that effect and it's now constantly refreshing and no matter what I do (respawning, deleting player data, restarting the server, clearing it with commands, clearing it with milk) I can't get rid of it. It keeps refreshing it's duration to 10, like it's being constantly applied to me. My friends do not have this issue.
I know it's this mod because removing it got rid of the effect. Also, adding it back did not solve it, I still have the incurable effect

Same issue here

i was hoping that maybe now that create is on v0.5.1f instead of c, maybe this problem would be miraculously fixed, so i tried installing it again. i spent a whole day flying around with the beacon running, working on other stuff, and no slow fall! i was so excited and thought that was it! then i removed the beacon and immediately got slow fall again. nothing i could do would make it go away. so, sadly, it's still broken. :(

have you ars noevau??

i'm also having this problem on a 1.19.2 server with a custom modpack. (no ars nouvea)

for testing, i made the most minimal of packs, with only the required mods, and i still got the slow falling effect as soon as i went into spectator mode.
