We just upgraded most of the computers in the office to Yosemite, and immediately started having an issue with ArchiCAD 17 updating placed external images on a teamwork project. They won't update; they appear in the file manager as missing. If we delete the file and try to place it again, it produces a blank square.
As several of us are working in teamwork, we have noticed that one of us can usually update the images successfully, but it almost appears random which of us has the "magic wand." Haven't completely tested all scenarios to determine, say, if it is just the first person who gets into the teamwork project in the morning. Regardless it is a serious bug that is interfering with our workflow.
