Modifying GameProfile issue

Hey there,
I am trying to modify the GameProfile JSON data but for some reason it doesn't work anymore when I modified it.
So I started off with making a simple skin changer that can be seen by the player itself as well. And then I tried modifying the JSON but even though the modified and unmodified are exactly the same (besides the timestamp is like 2ms off), it still stops working after I modified it. This might sound a bit confusing but it might make more sense if you take a look at the code:

Original unmodified JSON:

Code:

Modified, but yet the same JSON (basically I recoded everything with base64 decode and all jsonobjects)

Code:

So basically my question is, why does a modified version of the GameProfile not work even though it's exactly the same as the unmodified?

 

@ThiemeH They're not identical. Try using this: https://text-compare.com/
The first one has 'M' while the second one has 'Q'.

 

'besides the timestamp is like 2ms off'

If you decode in base64 you'll find out the timestamp is a few ms off but I doubt that stops it from working

 

@ThiemeH Why not just set the texture of profile1 to the texture of profile2?
