I’m having this weird issue where data from a specific attribute disappears without leaving any history. It’s happened on several projects. For example, Obj2 will have the attribute App == 4, and after baselines later this data is gone. There was no action in this object, just cleaning of suspect links and baselines. Any ideas?

1st though is to check the attribute definition, does it have history turned off? The other is that when you baseline the history goes away from the current and into the baseline of the module so it clears it in a sense.
