When I open a session that has Omnisphere, the patch itself is still loaded but doesn't tell me what sound bank it's from. It looks as if I just opened a new instance of it. I have to manually search through all of my banks to find what sound its from. It's very tedious and annoying. I'm on version 2.5 but I don't think updating will fix the issue as I had the same problem on an earlier version.
