So it is a very simple suggestion.
Since a couple of years ago, it was decided idk by who or why that private interiors would be restricted to the group itself only / gangs/ squads only.
I understand that it is cool to have something that only your squad can see but what is the point of having a super duper cool base interior if nobody can actually see it ?
When that restriction was added some part of the RP side of SAES died with it too, it was pretty cool to actually get inside gang interiors to RP, spy or whatever as HLS for example.
Some groups i understand that would need to have that restriction in some areas of their base such as DE or CLO but for the rest ... comon, it was dam cool to get inside bases.
