I,m working in a boygroup setup this days and found some strange behaviours.
This one is easy to reproduce:
Make a boygroup setup 1 server 1 client for example, make some nodes and control+B so you will see them in the clients.
Now make a timeliner node + control B and create some values inside timeliner.
Save the patch , close vvvv and open again in boygroup.
The patch or subpatch that has the timeliner node inside will show as empty.
