v1.5.2

Fixed

• Correct raid difficulty & instance on exported loot. The difficulty and instance were read from wherever you stood when exporting, not from where the loot dropped — so exporting after leaving the raid (e.g. from a delve) stamped Mythic-raid loot with the wrong difficulty (seen: difficulty 233 / "Mythic – Flexible Raid" from a delve). Loot now uses the instance data RC freezes at the encounter. This also unblocks sync: the bogus out-of-range difficulty id was making the server reject the whole reconcile payload.
