Tested with 1.18 against Angel Rings, Endless Abilities, Mystical Agriculture, and Magic Feather.

With DML:Reforged installed, all other forms of creative flight drop you out of the air when you change item in your hand or have any update to inventory (like getting hit and your armor taking damage.) DML's glitch armor works fine to fly, with no issues on taking damage or changing items in your hand.

With DML:Reforged removed and all four other mods installed and active, all of them function as intended (with Angel Rings taking exp if configured, Magic Feather giving flight within range of bacon, etc all correctly.)

This is 100% the fault of this mod, I made no other changes besides disabling DML:Reforged and the only other mods installed were required dependencies of the five listed mods (your's + the other four.)

Totally agree with Grath as my own 1.19.2 pack with a lot of mods I have been trying endlessly to find what mod is causing any flight mod item from cancelling when scrolling the toolbar onto any item.

Finally found it to be dmlreforged-1.0.7 which seems very weird as it doesn't have need to effect items that add creative type flight, hope this is fixed soon.
