Okay so this has only been happening for the last coupld of days but it's super annoying and makes it pretty hard to play. So firstly when I see a textscreen it puts this strange 1x1 square right in the centre of it but only I can see it. Secondly I tired putting my shop dupe down but it didn't seem to have any textures. I've tried relogging and downloading the Zarp content pack but nothing has worked. So if someone could tell me why this is happending and how to fix it that'll be great.
