Scientist Outfit - Missing Graphics/Pixels in legs

Wow, I haven't posted here in a long time.

Anyway, I discovered this bug when someone had made a Trenchcoat mod that you can find in the steam forums, (called Longcoat Pack) which is basically a recolored Scientist Outfit.

But I discovered a graphical error that, at the time, I thought was just from the mod. I"ll just copy and paste the conversation I had with the author, along with screenshots.

Me: "Found a bug: The character's leg seems to be exposed when standing idle with the "personality" pose that is similar to the character standing still while holding items."

Me: "Picture for reference. Tried the black coat too, the same. So probably all of them."

Mod Author: "Thanks, I'll fix it later tonight."

Mod Author: "Okay found it! That was kind of a pain in the ass to find, but I got it. That means it's also a problem with the vanilla Scientist pants, interesting..."

It didn't dawn on me until now when I actually tried on the vanilla Scientist pants that he was talking about the base game. His mod is fixed now, but as you can see with this image you can clearly see the same missing pixels with the default Scientist pants. (Probably have to zoom in to see it.)

Mind that this is only when the "idle" animation of the character is of that exact pose. The rest are probably fine since no one has reported it.
