[Export bug] Problems about the exported engines

[ExplodingKonjac]

first, the engines have a terrible response time. when i press 'z' or 'x', i need to spend a lot of time to wait it to start up or close completely. and i didn't find any button or input box to change the respones time.
another serious problem is that the engine doesn't show the plumes! i exported the mod and open the game (it took much time!) many times, but nothing changes.
hope you can repair the bug soon.
