I have warp stabilizer applied to many clips on timeline. But the effect is not staying applied in many cases. When the playhead is later placed over a previously stabilized clip, or an export is started, I find the clip needs to be analyzed again. This is under 14.9.0 Build 52. Extremely annoying.

I've also noticed that sections of the sequence I previously rendered are no longer rendered, and nothing has been changed on the timeline there since last rendering. I haven't had time to chase this down at all.
