Nodes Displaying strange behavior!

Hey all! My nodes keep doing this weird thing where they kind of collapse but I can’t open them back up and its causing massive problems with my projects? Any idea whats going on?8bfdb64eac7bb36f9b1b399b841a929f67b8376c.png

That is odd for sure. I’ve never seen anything like it either. Which nodes in that picture aren’t opening back up? I can tell the multiply node is missing an “A” pin, but is there any others i’m missing?

It seems you’re in the material editor. Does this happen in any other editor, like the event graph?
