I never saw this bug until I made a few changes to my Fallout4/Fallout4Custom.ini file. The only changes I made today were related to uGrids and specifically these two lines: bPreemptivelyUnloadCells=1 (I didn't have this line included before today)iPreloadSizeLimit=16777216000 (I had this set to a much lower value previously. This amount is what I've read to be correct for 32gb ram) About to try testing.
