Projects show up greyed out in File Select dialog for “Place Hotlink…” if they are already opened by another user who uses macOS 10.13 High Sierra.
It is due to Apple’s significant changes on how smb works in the background.
To prevent this issue use Teamwork files as hotlink modules instead of Solo projects.
We are planning to fix this issue in a future update.
