I'm having problems with MechJeb causing spacecraft to twitch randomly when on autopilot. Basically anytime it's using a Smart A.S.S. function, including landing guidance and maneuver planner. Has anyone else had this problem?

I've just started getting this problem. Has anyone come up with a workaround, or way to reset MechJeb?

#293 may be related - see if setting your mechjeb pod as 'control from here' helps

I edited all my command pods to have the mechjeb module in them. I don't have a mechjeb part to switch to.

Yes.

If you have a look in the attitude adjustment window, you'll notice that many of the values periodically jump to infinity when it twitches. It appears to be dividing by zero or something like that

May be related to the older audio hiccup?

Closing this as an old MechJeb issue. Many MechJeb issues have had little interest in years, have been fixed for years, do not include adequate replication steps, refer to old problems which are no longer applicable, or are difficult to determine what the problem is. This issue is being closed for one of those reasons. We apologize for any inconvenience, but keeping the TODO list tidy helps the developers.

If this bug/issue is still a problem, please open a new issue. For bugs please try to include a Minimal, Complete, Verifiable Example that explains all the steps required to replicate the issue. A link to the KSP.log file should be ideally included, but is often not sufficient information. Screenshots or short videos are often the best way to show a bug.
