Thanks Padishar, very thorough. I've corroborated your conclusion that it's not KER-related by uninstalling KER and confirming that I can replicate the glitching. Still an issue, but not KER-related, so I'll take it out of this thread. EDIT: It appears the true culprit was Contract Configurator, FWIW. Started with clean install and added back in mods until glitches returned. Confirmed removing CC eliminated glitches. Damn. No anomaly surveying for me for a while
