This is a reoccurring issue that has become more consistent. I am editing the cells of an interactive schedule, but when I switch over to the floor plan and come back to the schedule any data I enter in does not stay/disappears as soon as I click a different cell.
This is happening in both Teamwork and Project files, but currently I am working in Teamwork and after this happens I try to release the schedule or send and receive and Archicad crashes.
