+	\underline{BASIC FUNCTIONALITY}
+	\begin{itemize}
+		\item With the LOCAL_Z option enabled, the PRT model's PRP package attempted to check that a particle release point's z coordinate fell within the grid's vertical extent before converting the coordinate from local (normalized on the unit interval) to a global (model) coordinate. This bug was fixed by converting coordinates before conducting checks.
