Mecanim state transition bugs

Unity Engine
1

My team has run into a couple of bugs with the Animator window of Mecanim which been troublesome to workaround. Are these known or fixed issues? We can’t upgrade past 5b18 yet, as we are waiting for a dependency in a newer build.

  1. Some installations of Unity Editor 5b14 and 5b18 can’t delete some state transitions in the Animator window, even if the controller and its meta file are writable on disk.

  2. When upgrading our project from 5b14 to 5b18 some state transitions stopped working. We found that recreating them with the exact same settings in the GUI fixed the transitions.

Unity Pro 4.6.2 Mac, the transitions cannot remember the transition offset and range,
I move the blue part in the timeline, focus on other transition, back to previous, ooops, forgotten!

Wth?
