Too late. The node had restarted.
But I can confirm this issue now again:
The node is still processing the bloomfilter from the 6th on US-1. Now the second time interrupted and resumed meaning that it created a new folder with date of today.
Still the same old bloomfilter.
So this data could be up to 3 weeks old when it finally gets deleted. If it was collected in the initial date folder, it would get deleted immediately with the next trash chore run.
