Can't Complete Geometry When Number of Pump Stations Exceed Number of Structures of Any Type

If there are more pump stations in the model domain than total structures (inline, lateral, SA/2D, bridges) geometry property tables will not be able to complete, preventing a model compute. Workaround: Add dummy internal SA/2D structures until total number of structure equals or exceeds the number of pump stations. 

RESOLVED
