I worked to reproduce the bug.
I reproduced the behavior but in certain conditions.
It seems only happened :
- after the settings changed from the drift unchecked to drift checked (but not from checked to unchecked)
- more often when the Hovercraft is in move.
I tried to move on circle just before pressing Escape to change the setting.
I reproduce with :
A fresh game (base 0.17.47 + Hovercraft 0.17.13 + Creative Mod 1.1.4).
I enabled Creative mod (with cheats) to directly create a Hovercraft and a rocket fuel.
I save my game, disable Creative mod, reload the saved game without Creative mod.
I still reproduce with different version of factorio and Hovercraft :
- factorio (base 0.17.47) + Hovercraft (0.17.13).
- factorio (base 0.17.48) + Hovercraft (0.17.13).
- factorio (base 0.17.48) + Hovercraft (0.17.15).
- factorio (base 0.17.50) + Hovercraft (0.17.15).
Do you suceed to reproduce the behavior ?
