Buried Takish'Hiz Raid maps

[benjcallaghan]

The map named "Buried Takish'Hiz: Emergence from Stone [Raid] (Gateway)" with the image name of "exp19_dun_takish_raid_01_0" should be removed. It's a copy of the lower-right corner of "Buried Takish'Hiz: Emergence from Stone [Raid] (Knowledge)", but with a different zone-rect to achieve a zoom-in effect. The original zone-rect for the Knowledge map is more accurate.

The Gateway zone was copied from the Contested version of the dungeon, where the Gateway is larger and has a different zone-rect.
