Interacting with a Trader or Trade Terminal while already having a window open causes it to bug out

As of two or three patches ago, interacting with a Trade Terminal or Trader while already having a window open causes a black square to pop up and bugs out the window, requiring you to close it and reopen it before being able to use it.

Here's a video showing the bug:

This bug is still around and is pretty annoying since if you accidentally click a trader a second time after putting something into the sell window the items vanish and require a re-log to be accessed again...

This relatively recently introduced bug is still around and needs to be fixed at some point, it's very annoying and even though it can be avoided bugs like this just contribute to make the game feel like a low quality product.

fixed now, thanks.
