When off the ground you have much less aerial control when you initially don’t have a jetpack equipped.
What I mean by that is, you can’t move in the air as much (Obviously not because of the jetpack use.)
What makes this a bug is, when you equip the jetpack ariel movement becomes unrestricted and taking the jetpack off doesn’t go back to restricted movement till you respawn.
I found this problem when I spent a few hours making a trampoline course, and then turned off jetpack use. Finding it was impossible to clear without previously having a jetpack equipped. (Or atleast flagged that it was usable.)
Here’s a video of what I’m talking about. You can see in the bottom right corner the buttons I’m pressing.
