No worries. I understood. I checked MVOs, layers, overrides etc and can't figure out why it won't show up. I think if it was something like MVO then it shouldn't show up in the first place instead of just the elevation view disappearing.
We had such bugs in previous versions. It was happening because we used not latest libraries for all windows, some of windows started to disappear. But this happened only when we had Merge uniform Items turned ON.
