Only took me about 3 years . . .
It looks like both the Lockjaw and Sanctorium use an identical map, or at least I think they do. If not, we have not lost anything, as we can add in the modified map as needed. For now:
Code:
<ImageStyle Name="exp01_rgn_sinking_sands_epic01_lockjaw" displayname="Lockjaw's Lair" menugroup="Desert of Ro" zonerect="-292, -241, 24, 189">
<ImageFrame Source="images/maps/map_exp01_rgn_sinking_sands_epic01_lockjaw.dds" SourceRect="0,0,436,593" />
</ImageStyle>
<ImageStyle Name="exp01_rgn_sinking_sands_epic01_lockjaw_undead" displayname="The Sanctorium" menugroup="Desert of Ro" zonerect="-292, -241, 24, 189">
<ImageFrame Source="images/maps/map_exp01_rgn_sinking_sands_epic01_lockjaw.dds" SourceRect="0,0,436,593" />
</ImageStyle>
