We're tracking this issue internally at a high priority, but so far haven't been able to reproduce it reliably enough to isolate the root cause.
At the current time, we're planning to fix it in 8.1 and "forward port" to 8.3.

Adding my experience with 8.3 in case its useful. Iāve had this issue happen three times now, when I try to save in the Designer, I get the error below. In the past, when this error has occurred, Iāve lost all my session props after reopening the Designer.
However, this time when the error came up, I had another developer working in the same project try to save, and he was able to save successfully. When I reopened my Designer afterward, my session props were still intact.
Not sure if this points to something with individual Designer instances or gateway communication, but figured Iād share in case it helps.

I ran into this issue today, PC server hosting a gateway was rebooted and all of the session custom props have disappeared. This is very concerning as it had multiple bindings that are crucial to making the application function. Any response from IA on how to fix this issue?
I found this thread when trying to create new session custom properties in a mostly empty project, one I had created a few days before and had left the designer open. I created a custom session property, navigated away from the session/page configuration screen to a view I had open, then returned and saw the property did not exist anymore. I did this several times with the same outcomee. I tried saving before navigating away from the session screen, but that didnāt help. After several attempts I just saved, closed my designer, re-opened it, and tried to repeat the process, but this time the properties I created were saving.
Interestingly, my designer showed my session with Session Position and Session Meta before I closed, but they are no longer there when I open it. This seems to be indicative of a bug writing where it shouldnāt be, because I donāt know why a session would need a configurable position property
