Hey all,
We have seen another uptick of this sort of issue in the past few weeks and the engineers have been made aware of them. Keep in mind however that we in Technical Support are not developers ourselves and won’t have most of the technical details on this sort of situation. All we can really do is continue to monitor for updates, keep it on the developers’ radar, and post if any new information is available. At this point in time this is being treated as a bug rather than a technical issue so there’s no troubleshooting we can provide you.
As a reminder, you can sometimes work around it by swapping between war mode or out of war mode to force a re-shard, but that won’t always fix it.
