If you hold space to ascend with the quadrocopter or any other one of the airships/gyrodyne and dismount it while still holding space bar it infinitely will count the jump statistic up. This messes with some things like a custom jump sound from other mods/packs.
Version 1.19.2-0.5.1

I can't reproduce that, does this happen without any other mods?

Here's a test with just immersive aircraft installed

no problem!
