I have an FC and I just finished doing a redesign. In my first design, I didn't really use any blank partitions but now I did and it came out great. A few days later a member, with zero furnishing privileges, pointed out to me they can remove any design of the blank partitions.
How can this be intended design? Any FC members can remove or change any blank partition design in the FC house. Imagine you have a mogstation wall and some member just decides to remove that design. Poof your wall design is gone and so is your actual money.
Same for the paintings, members with no furnishing privileges can remove or change paintings in the FC house. I realize this is not as bad as walls but still, I can't imagine this to be intended design.
For private houses this is not a huge problem as you need to share your house before people can interact with it so the number of people that can touch (and destroy) anything is under your control. But for (large) FC's this is another story. Any FC member can touch and remove any blank partition design without having the right to do so.
What makes it even worse is that when you go to Character Configuration > Display Name Settings > NPC's > "Housing Furniture" you will see that it is set by default to "Display always". In other words, members who come into your FC house will not only be able to destroy blank partition walls but they will also find them really easy since those walls will have big arrows pointing to them (unless those members change the option to hide the arrows). And we all know human nature, when there's something interactive we like to interact with it.
It baffles me they couldn't just make the interaction with blank partition walls a simple housing menu thing (so you would have to actually open the housing menu to be able to add new paintings or change wall designs). Or they could have easily implemented an option in the FC Rank Hierarchy settings itself to make walls and paintings non-interactive for members who don't have the rights.
I hope they will fix this eventually.
