We have been working with a combination of Notes 8.5.3 and Source Tree since more than a year and things were moving smoothly, however, recently, after an upgrade to 9.0, what we have observed is that, the designer project doesn't completely sync with the on-disk project. Not sure, but manier times the new element/custom-control is sync'ed correctly, however, an changed element would not be replaced correctly.
Strange thing is that it happens RANDOMLY, when we open the on-disk project, everything is in there correctly, however, even after manually performing the sync operation from designer, certain times the design won't be in the right state.
It is really a strange issue and not really sure if anyone has actually faced such a problem, however any suggestions here would do a lot of help.
Thanks.
