Hi all.
I am creating profile runs using the "hydraulic run from node" function. It was working fine until I tried to run profiles that contained a specific manhole. When this manhole is part of the run, the program responds as normal to my request to create a profile, but instead of generating the profile I just get this error message. I tried deleting the manhole entirely and placing another one, it did not resolve the issue. At this point I'm out of ideas. Any and all suggestions are greatly appreciated!
