Question about Mesh Bed Leveling and resuming a print at a failed location

I have a MK3S+ MMU2.  23 hours into a print one of the filaments jambed on the spool an would not feed.  For some reason the print continued Without filament until finished three hours later.  The filament was chewed up at the gears as expected which threw a filament misfeed at the end upon completion.

There was nothing wrong with the print and could easily have been finished by a print resume from G-code line or similar. Is there such and animal in Prusa??

I gutted out all the G-Code that had completed up to the point where the nozzle ran out of filament, made sure to comment out the M80 Mesh bed leveling as well as the purge line and set Z axis during initialization high enough to clear the printed objects. 

However, during initialization the print head still tried to do what appeared to be a Mesh Leveling move.  The move contacted an object and and faulted, giving an error telling me the move could not find a magnetic surface or similar terminology.

My question is,  during initialization, is there a move to locate Z zero based on the PINDA probe?  My hope was that as long as the printer had not been reset or turned off, the coordinate offsets for mesh bed leveling etc would still be in memory and the newly loaded g-code could command or resume starting at the failed location height.

Any thoughts, what am I missing?
