We're trying to edit a project config using the most recent build, but it appears to be very unrealiable. The stage being edited is consisting of basically three groups, each having 5-8 items (same variable setting, Visual Studio build, some output file moving and resigns).
The stage editor appears to basically at random delete actions from the groups. I just added a Visual Studio build action I know for a fact that I already added. Now after saving the stage it appears that the last three items from the stage were lost.
Thanks for reporting this. We've done some further testing, and have found that actions can be orphaned (and therefore not saved) when copying and pasting on to a parent action. We've fixed this and will do some further testing to ensure there are not other cases where this happens. We hope to release a new build incorporating this fix later on today or tomorrow.
