Thanks for the replies everyone and no worries if you have no further screenshots. If you see anything like this again in future though with missing textures, do try to grab a quick piccy if you can so I can pass this on to QA.
Thanks for also trying to verify your game files, I wanted to see if this issue could be a quick fix to one of the game files, but sadly that's not the case.
I will forward the images from this thread to our investigation, so thanks for providing them. Hopefully, we will be able to patch this graphical glitch in an upcoming update.
