The classic old fixer grid has been around a long time. Perhaps it is time for an upgrade, especially in light of some recent changes limiting fixer mobility and usefulness. Perhaps a combination of the existing f-grid structure, but each playfield would have a room similar to that for notum miners, with from 6 to 12 locations they can exit into that playfield. Further, at the current existing f-grid exits perhaps a device where fixers/teams could re-enter the grid.
