Every time I close and reopen XCode 6 beta 6, my previously-happy constraints are messed up and I have to click on the yellow dot to get to the "Misplaced Views" thingy, then click on each yellow triangle, choose Update Frame, and click Fix Misplacement to correct the problem. Is this a bug in the beta or have I done something wrong, perhaps? Constraints in XCode (to me, at least) are horrible things to tame at the best of times, so maybe it's not a bug?
Once fixed, and XCode neither complains about nor renders the widgets badly, it's fine. But as soon as I close then reopen the project, they're messed up again.
