Please forward this to Qouteall if possible.
In the "Immersive Portals" mod, jumping into a Immersive nether portal at a certain angle will cause you to phase through the portal without going in it.
This situation is almost impossible to avoid.
This is NOT a suggestion.
FYI, this did NOT take place in 1.21.1.
1.21.1 is the closest version to 1.20.4 I can find.
