What happened?

Two equipped bunny hoppers (Artifacts) = infinite flight.

It can be reproduced easily, simply equip two bunny hoppers, but I believe it needs an extra item slot which requires a belt.

I can confirm that the bug is true. Equipping 2 bunny hoppers relic will becomes an infinite jetpack. You can still fall and take fall damage if you let go the Jump key.
