Invisible person bug

Hello, i have a bug that i just found out, it's someone that is invisible, i even have a screenshot for more proof if you want some more evidence:

As you see, the player is invisible if you look closely, i was thinking to post it here so you can fix the bug.

Q1: If this is not a bug, say why.

Q2: If you think i made a mistake, comment about what i did wrong

Q3: If you dislike it, say a reason so i can improve it :)
