Ok so this is what happened:
I luckily had a 1015 credits to buy the explorer's top and bottom so I went to Shruken Ned's to buy them. I bought them and I looked in the "stuff" section of the toolbar to make sure that I had the costume. It was there but I had 2 explorer tops and 2 bottoms! but I only bought 1 top and bottom. don't you think that's weird?
