Prusa MK4 spontaneous reboot at filament change; screen shows 60% done

On different projects and with differenct filaments
-the printer correctly pauses and the filament is extracted.
-the printer re-boots
-the printer pauses, apparantly to warm up
-the screen reports the job is 60% complete; the job is usually more than 60% done
-the printer pauses, apparantly to warm up
-the printer restarts at the correct position, but with no filament loaded.

Changing back to 6.1.2.bbf had no effect.
The printer had been working for several months before this issue arose.
