I am going to assume this is related to the same restriction that applies to regular space platform in space, when attempting to make use of quality space platform: In that it is not placeable in space.

The same seems to apply to SPfG , in that making and storing Quality SPfG is perfectly fine, but placing it while in remote view reverts the construction request to Normal Quality SPfG.

Holding it as the player and placing it down seems to work like with other quality tiles: It reverts the quality to Normal.

Anyway this can be forced/fixed?
