Everytime I play Minecraft everything works normally except for how Character Creator and the Marketplace loads. Keep in mind that my internet connection is fine and I can join online servers and worlds and this issue remains the same everytime I load Minecraft.

In character creator, none of the pictures for clothing items show up, but the rarity and indication for minecoins, free, or achievement unlocks are all there. If I click on one of these, it functions as normal and you can buy it except for the fact that the pictures for the items on the selection screen itself doesn't load. This also happens with emotes and capes. Note that even though it shows that Steve isn't wearing a cape below, the cape still shows and this is because there is a little lag before showing an item after selecting it and I took the snapshot before the image was fully loaded. There are some exceptions though, and I've found these are: The Steve and Alex clothing items and a little more than 10 pieces of headwear around the same place. 

I included the marketplace in here because it has generally the same problem. Most items bought on the marketplace don't show pictures, but instead just a moving loading bar. I want to point out real quick there wasn't any loading bars in the character creator issue. It seems to work fine other than loading visuals like worldviews and you can still buy items like normal. It also shows tags like offer.category.new which may relate to the problem.

The last thing I found is that when I try to create a new world with one of the marketplace worlds, it actually shows the picture that should be on the marketplace. I hope you can fix this soon.
