Short description of error
when working with meshes, sometimes you can't click on a certain vertex anymore. (double-tapping TAB helps for now)
Exact steps for others to reproduce the error
This happens at random times when I'm working in Edit Mode. Usually it happens to a vertex that I have just moved, then went to another vertex and then try to click on that vertex again.
