Description of the bug

When using a MMU, if you set a specific wipe tower extruder, generated support disappears after the gcode preview window finishes loading.

In the attached project file, under Print Settings -> Multiple Extruders, with support set to "support enforcers only" (the state it should be in, in the project file), if:

Support Material/raft/skirt extruder (setting E4) is set to 6

Support material/raft interface extruder (E5) is set to 6

Wipe tower extruder (E6) is set to 6,

and I click , the model will show generated supports in the unshaded gcode preview colors, but when the program finishes loading and the shading comes in, the support material disappears. If I then export this gcode to a file, there is no support material in it.

If I change the settings to

E4: 6,
E5: 0 (default to minimize extruder changes)
E6: 6,

and click , the model generates identically, but the support material from the bed surface at the edges of the model disappear, leaving only the support raft interface layers

If I change the settings to

E4: 0
E5: 0
E6: 0

and click , support material generates and is savable in the g-code file.
