Will it become free in future after we bought it? so we can always switch between them. or do i lose it if changin to other hairstyle. Thanks for answering.
Simple answer: No, it won't. You'll have to pay 6 rp again to change your hair/face back, even if you had that hair or face before.
What Kivin said, though I'd love the ability to store away things like Donor hair/faces to be changed at will later. I have no clue how such a thing would be doable though.
It's definitely possible if the developers wrote the code to store purchased hair/face ids to the database. I'm not sure if it's worth the trouble, but wouldn't mind having this donator perk added when the beta is nearly bug free.
I'm not sure if its GMS or another server, but I know you are able to save like, 3 hair style and 3 faces. Not quite sure if it's 3 of each or 3 total. If it can be implemented at all, doing it with a limit of 2 or 3 might be nice! I personally don't change my hairstyle all the time, but I know I would love to have a couple more options for when I want to change my look around. The only thing stopping me is the price tag haha. But if it was permanent (at least for 1 or 2 more) I would be more than willing to shell out for this haha. Then if you really want to get something else, obviously you will still pay for it ^^
Actually it's in GMS and its 3 each(for hair and faces) and for free. If you want to have more slots you have to get them via nx. I really love that option because you can always get back to your favs looks
