I'm new to mapping, and this is my first bug so it's probably a simple fix. Every time I try and change the vertex of something this weird invisible blue ufo box keeps stopping me. And it's ruining the flow of my novice map making. It can only be selected in vertex tool, and by select I mean it blocks me from changing the vertex of anything by selecting itself. It can't be slanted or deleted (I want to delete it I tried to find a shortcut but the dev site is down found out it was just the delete button, can't delete it through the edit page either). I can change the size and move it around; the redo/undo/paste page pops up when I right-click in 2d. This only started happening when I started using the vertex tool, I think, at first it was a 0 x 0 dot, but I started playing around with it trying to fix it myself, and then made it a size people could see for a picture.
