I'm assuming somebody didn't update the textures to the suit from the last 0.62 update which is where they tweaked the ghillies but when the woodland suit isn't in the sun light it seems to be fine but when it is in the sun light it just turns bright green like that.

you can easily tell its a glitch look at my inventory and you can see what its really suppose to look like, but when the sunlight hits it then it looks light green.
