Stock Toolbar Unresponsive

[StrandedonEarth]

One of my ships appears to have picked up a bug (or is it a baby kraken?) When trying to dock two ships in cis-Dres space, I realized that the stock toolbar was not responding at all, to hovering or clicking. All three crafts in that SOI have the same problem. When going back through the KacBackup saves, I found that my supertanker had picked up the bug on route to Dres, with the last unbugged save being over a year ago in game-time. When focussed on other ships in other SOI's, or at KSC, the toolbar is functioning normally.

For mods I have VOID, KAC, ThrottleControlAvionics, ForScience, NF-DAI, Asteroid day, and StockFuelSwitch. StockFuelSwitch uses a FireSpitter component which comes up as "incompatible" when launching the game, but I've used it like that since nukes went LF-only with no problems.

Outputlog

Quicksave

For the output log I switched to the problem ship, quicksaved, then exited, so all the errors it threw should be at the bottom of the output log

Can anyone tell what exactly is causing the problem, or has anyone run into this before? Can it be fixed, or do I have to write off the last year of gametime and do it again?

Update: I found the point where the bug bites. This Quicksave loads to the "Dresbound CRV" where the problem appears to start. Everything is working fine. Warping ahead, sometime within the next 10 days or so it bugs out, and the stock toolbar (I don't use blizzy's) stops responding. Clicking the app section of the bar does nothing, and hovering or clicking over the far right side of it does nothing.

Here's the log of when I was trying to find the exact point where the bug bites.
