Mask Editor taking a long time to process a small adjustment

Issue likely solved. When I started the project, I imported the baked mesh maps to 'current session' rather than 'project project name'. This probably led to Substance having to comb through my pc looking for them everytime a calculation relevant to the maps is being made.

Now after properly importing the maps, any new Map Editor generator works reasonably fast but the old ones are still lagging the same way. Copy and pasting the generator doesn't work so I need to make a new generator and copy the settings from the old one as a workaround.
