My friends and I are building a game using unity and everything was going great in 4.3.4. The new update came out and we updated and the game is working still as designed but when we go to move and edit the placements of sprites with 2D polygon colliders. CTL clicking to snap to grid now deletes vertices of the collider. We are also having problems shift clicking and trying to select multiple sprites no longer works. We are at a loss as to what changed between 4.3.4 and 4.5. I am not sure if I am explaining that well but help would be appreciated and I can get more info if that would help explain the problem.
Im having problems with the 2D editor too, check my thread:

Hopefully someone will listen and fix these issues.
