This is the summary of the bug please fix it, IT IS A OFFICIAL SKIN. IT NOT SUPPOSSED TO BE THAT COMPLICATED. I REALLY LOVE THE SKIN CMON
I have seen reports of this bug already from , but it doesn't look like it ever got fixed.
Steps to reproduce:
Purchase the LEGO Minecraft Dragon Slayer set
Find the brick with the code on it, and redeem it
Download and set your skin to the LEGO Minecraft Dragon Slayer
I think the issue is that the skin is automatically set to the slim arms style (like Alex), and it is supposed to be the full sized arms style (like Steve). I tried importing the skin into a skin editor, and it automatically sets the style to full-sized arms. I noticed that the holes in the hands (like a LEGO Minifigure's hands) look correct, unlike the slim-arms one (attached below). I can also see that in the skin file, the arms are 4-pixels wide, and not 3.
I think all that needs to be fixed is the skin needs to be updated and automatically set to full-sized arms, or updated to have actual slim-arms.
The advertised skin has 4-pixel arms, lol (see attached image)
This issue will not be fixed, see MCPE-50154.
