Unable to see certain skins

So, I've been having a few problems with my minecraft lately. This is the first crash report I've done and I don't know what caused it. I was in normal gameplay, warping from the Nether to home on a public server when it happened. I've also been having problems with seeing skins, I can see a few but not all of them and they show up as Steve's and Alex's randomly, sometimes not even on their respective body types. I've tried re downloading multiple times but I don't know what the problem is. I'm sorry that I can't type this in the format you have given me but this isn't a bug for anyone else and if it is, very few people have it. Minecraft for my friends works fine and they can see every skin correctly when i have to use a website to look at people's skins. Ant_1105's skin show's up as an Alex even though his skin is shown below and I've taken out the other players name for their privacy but their skin shows up normally.
