While extremely funny, this is still likely a bug and should be reported.
If a user dies while their jetpack is active (holding spacebar), they will continue to use their jetpack in death. This will continue, even without user input, until they respawn.
How to reproduce:
- Hold spacebar while jetpack is equipped
- Die in any way while continuing to hold spacebar
- Once dead, let go of spacebar (as to not respawn)
- Bug will occur
Attached below is a demonstration video.
