On multiple specs, I've seen instances of DoT counts being reset prematurely when the DoTs haven't fallen off. Most notably this happens on specs that don't see some sort of auto-refresh or secondary hits occurring regularly -- e.g. seen more on Balance Druid than Shadow Priest.

Investigate the root cause of this and how to mitigate it.

Possibly has something to do with TRB.Data.snapshotData.targetData.targets[guid].lastUpdate not being refreshed appropriately and the resulting target being cleaned up before it should.

Haven't seen this since I made adjustments. Closing.
