Attached Properties aren't accessible in Report trait after a Delete

[riverwanderer]

Standard properties continue to be available to the Report Action trait after a piece has been Deleted.

This is not the case for Properties accessed via an Attachment.

Here is an example Report Action that references properties as follows:
MustRetreatHex is a Dynamic Property on the piece, unit is an Attachment name and Strength is a Dynamic Property on the attached piece:

Report output after a Delete:
* Attacker: MustRetreatHex=1 unit_Strength=

Report output if the Delete is blocked:
* Attacker: MustRetreatHex=1 unit_Strength=3

Workaround; don't rely on the standard post-delete behaviour of the Report Action trait. Instead, use a Trigger to ensure that the Delete occurs after the Report Action.
