The planet plate with the faction module works completely like it should.
The other 11 planet plates suffer from 2 issues as far as I can see:
- any faction member can place a new faction module down on them, this causes all planet parts to lose their faction signature, including the homebase itself that gets removed completely.
- the faction permission rank set on the planet plate with the faction module only applies for that planet plate. If you set it to Faction leader only, only a leader could edit that 1 planet plate but every member could edit the other 11.
