Kruise Kontrol has some compatiblity issues when used with the jetpack mod (required by space exploration):
- It can't steer properly while flying
- When landing while KK is enabled, the green line remains on the map permanently
The first one is no big deal for me, since I can just land to make KK work. The second one is more annoying, since the effect is permanent.. It would be nice if you could make the cleanup logic more robust, so the green lines get removed even if it's cancelled by landing instead of a normal cancellation. Or simply prevent KK from being activated while flying (or more generally not walking).
According to a thread on the original KK mod, this can also happen with trains in vanilla factorio.
