Getting some odd behavior out of the Z-Pinch Aerospike. If I have it in Atmosphere mode, my log is spammed with NREs

It seems to reference Mechjeb, and indeed MJ will either function sporadically, or the entire interface will disappear until I switch to Lithium and then back again.
It may or may not be related, but on ascent, once I was in space and switched back to Lithium, the game has crashed twice when I go to adjust the ISP. A crash report folder wasn't created, and there's nothing suspicious near the end of the output log.
When I relaunched the game, my last save had been on the surface. I noticed that the max thrust reading on the engine was hugely negative, and after a brief reactionary firing of the engine to correct for a loading bounce, all of my LqdDeuterium was gone. (must have happened after this screenshot)
