I am working in OpenFlows Sewergems edition 3 verison 10.03.02.04. Recently, I have tried opening a profile I made when I first started using this model and the error message comes up that "H&H sewergems stopped working" I am not clear why this has happened. I have changed some locations where the catch basins connect to the conduit but for a while it was showing the profile with no problems, however now it seems that I can not open the profile in any of my scenarios without the error message popping up.
One of my colleagues found the cause of the issue. This error message is occurring because there are inactive tap elements on the profile. You will notice that the issue doesn't occur on all profiles, just ones with inactive taps. If the taps are active, the profile will open.
This issue will either be resolved or have an updated user notification in a future release of SewerGEMS. The reference number for that is 561872. In the meantime, this workaround has been added to our wiki page: Error opening profile in Storm-Sewer products: Index out of range. Must be non-negative and less than the size of the collection.
