/confirm This came up also on devcord. It looks like evac_center_13_z2 was migrated to just open air in #66123, I assume author missed that this very specific one was used as a mapgen update target for Dino Dave's mission.

Should be able to place the special on any arbitrary OMT by offsetting it from dave's position using location_variable_adjust

This doesn't account for rotation so it might be best off it by making sure dave is right below the spot it will be placed - thus you just need to z-adjust once or twice, and the x and y coordinates are irrelevant.
