Wait, how did I unlock all 5 costume slots at level 36?

I was positive that this wouldn't work, but it did. Here's the scenario:

At the release of Demon Summoning some time before I18, I created a Demons/Thermal Mastermind with the intention of making him a hero. I got said Mastermind to level 32 and put him on hold before I18 rolled out. He's been on hold until earlier this week.

I spent the last few days getting this guy to Paragon City, doing Rouge and then Hero Tips, and when I finally hit Paragon City, I realised I could take missions from Serge and Lauren - the costume slot missions.

My Mastermind had four costume slots unlocked before he left the Rogue Isles. He had his default one, he had his Halloween costume slot, he had the costume slot from the Facemaker and he had the one from Gorgeous Glenda (was it? The one in the Cap Facemaker). That's four slots. So I come into Paragon City and immediately snag a mission for Serge, thinking that I'll just do the mission and not unlock anything new, like what happened with the Cape arc I did beforehand.

To my surprise, I just walked into the Steel Canyon Icon and was given the choice to edit my fifth costume slot. And my question is: Why? Actually, I suspect I know why - I'm somehow not tagged to have taken this slot, as I didn't take it from Serge, so I got the same slot twice, but... Isn't this unintentional? Wouldn't this have been one of the first things to make sure wouldn't cause a conflict when Side Switching was being planned for? Did I meet some kind of odd bug? Is my character just too old? What gives here?

So what do I do about this? Report it? Not us the slot? Should I do Lauren's costume mission that I have already started? Should I do Carson's mission coming up soon? Should I try to cash in another set of Halloween salvage at Annah instead of Granny Old Woman? What?

Sounds like a random most likely one-off minor bug. Probably best to just let it go, not worry about it, and just enjoy having your final costume slot unlocked early.

Now I need to figure out what to do with it

Try Lauren's mission and see what happens ^_^.

It's not a bug at all.
It's been confirmed that via side-switching you can get your slots early and that it's WAI. However, even if you do all 7 costume slot missions and hand in a set of salvage, you cannot get more than 5 costume slots (+1 uneditable for VEATs).

I prayed to Satan that he'd unlock all of Sameul_Tow's Mastermind's costume slots and he did! You're welcome.
