filament unload in the middle of printing the purge tower
This is a new one for me. I've done many manual color changes and until today, the printer would do all its cooling moves and move to the unload/load position to do the filament change.
Today my printer started unloading the filament for a color change over the purge tower and never presents the normal "is the filament unloaded" message. If I remove the filament when it unloads and try to load a new filament, once the filament is detected by the filament sensor the printer resumes printing without loading and of course nothing is extruded.
This is the first time I've tried the manual multi color with the non-IS profiles on the MK4 and its possible i missed a setting, but if so I can't find it.
Any ideas?

Don't know if it helps but I use Joan's post from this as a check list: https://forum.prusa3d.com/forum/prusaslicer/manual-multicolor/
