Room wll height question

[menardrs1]

In the process of changing a ceiling height setting I now have an undesirable drop in my wall.


I have looked at both the ELEV and adjacent HALL (shared wall) and cannot figure out what is creating the gap at the ceiling.


...and the Hall specs.


I have included, below, a plan and Framing view to show you what the framing looks like. You can see that the HALL wall is the correct height but the ELEV wall is lower.


Perhaps I suffer from the "Forest for the trees syndrome" and need someone outside the forest to help me figure out how to correct this.

Thanks,
