I'm using the Jetpack mod (https://mods.factorio.com/mod/jetpack), and the Kruise Kontrol is unable to control it!
A quick solution will be disable this mod when the player is using Jetpacks...
The ideal would be to be able to control the player with Jetpacks!

Thanks.

I changed locally to stop activating this mod when Jetpack is active:

You can use this if you want!

For Jetpack, I recommend using https://mods.factorio.com/mod/move-with-mouse-updated. It moves in a straight(ish) line so it's not so good for walking, but for flying it's better. It's a different key (middle mouse button) so you can use it together with Kruise Kontrol. One for jetpack, other for walking.

I installed and tested this mod, but it has a serious bug. Half of the times I put a target with the mouse, when the character reaches it, it continues to walk indefinitely, shaking the entire screen... Sometimes I need to click 10 times with the middle mouse to be able to stop the movement!
But it works better with Jetpack!

Thanks.
