'Delete to here' and Context Blocks changed?

The ‘Delete to here’ function seems to be playing frustratingly with the Context Blocks, in that it'll leave the context blocks in place, even for an event that has no longer happened.

Example scenario:

1. Narrative: I walk into a tavern

2. Narrative': There's a fight between two NPCs

3. Narrative: One of them kills the other [context block adds: one of the people in the tavern killed the other person]

If I then Delete to here back to #1, the context block from #3 (that narratively no longer happened) is still there. So when I walk into the tavern there's probably a dead body already there.

It's very frustrating and seems somewhat inconsistent - some of the context blocks seem to change but others don't. Seems to be the same way across different campaigns.

Previously they used to delete blocks that were created after the delete-to-here point, which makes sense.
