Moar-Grid (and Moar-Grid-Krastorio2-Compat and Moar-Grid-SE-Compat) adjusted the grid size of armors by overwriting the armor with a new custom grid definition. This had the side effect of making it so you couldn't use certain equipment (such as jetbacks or life support equipment in Space Exploration) in armor you should have been able to. This fork is basically a reimagining where instead of redefining the armor with a custom grid, instead the base grid width and height are changed instead. Same effect, still able to use equipment you should be able to. Settings are the same as in the base mods, so just remove those and install this and it should just work out of the box.
