This looks like it was some kind of IA failure, but since it occurred over a month ago, it’s hard to diagnose why. I reissued the same IA job, and there was no failure, and I am now seeing new bounding boxes. Please let me know if you see the issue again.
For WB-768, we are waiting on the issue to occur with your newer imports. If it doesn’t, our fix worked. If it does, then a new fix is needed.
