Brief Description:
Returning from the End disables my Main World Fly and resets its speed to 1.

Instructions:
1. Enter the End.
2. Return to the Main World.
3. Double-jump like you're trying to fly.

I will note in this section that I only have FlyPlus, not FlyPlus2 for the End, so unsure if having the feature matters in recreation.

How many times did you recreate this?
I successfully re-created this twice; @ClarinetPhoenix said she also recreated it on Ediousieg.

Result:
The Main World Fly is disabled, and when enabled again, is reset to speed 1 (mine's usually at 10.)

Expected Result:
Typically, re-entering areas I can fly in from ones I can't results in my original Fly status/speed returning to what was set when I left the area.

Evidence:
Nothing shows up between switching worlds to indicate speed/fly status changing, so not much to show.
