Bug #26913
NullReferenceException: Object reference not set to an instance of an object
0%
Description
There are two issues where I see this error and I believe they are both related.
Issue #1: When attempting a crewed Mun landing at the Farside Basin, at some point I get horrible lag (graphics get jumpy, inputs take 2-3 seconds to respond). I'm still able to land, but after doing so I am unable to use the menu to go to Kerbal Space Center or the Object Tracker. As far as I can tell, the lagging seems to happen around the time of the autosave (but I'm not at all sure about that).
Issue #2: I've seen this issue on both the Mun and Minimus. When taking of with a lander to attempt a rendezvous with the mother ship, I will not experience lag, but I get the issue with the menu not allowing me to return to Kerbal Space Center or the Object Tracker. Additionally, every time this happens the graphics make it appear that the RCS thrusters are active on the mothership (though no monopropellent is being used and the RCS indicator is off).
The only way I can exit the game in these instances is to CTRL+Tab to a terminal and `kill -1 <pid>` where <pid> is the process ID of KSP. When I return to the game, I'm returned to a point in time prior to any of these events (and usually the second time is more successful, though I haven't had any luck with a "permanent" landing in the Farside Basin). This is severely hampering game play.
I am using no mods and though I have both the Breaking Ground and Making History DLC, I am using neither in this scenario.I am attaching a (truncated, the last 100K lines; can provide full log if necessary) log showing the error (and subsequent stack trace) for when this issue happens. This only started happening after the upgrade to 1.11.0.
