How do I delete Line Sources inserted through Pachyderm?

It’s so annoying the red circles show on your screen but you can’t select them to customize their properties like point sources or delete them :sob:. What do I do???

Edit: Also, my Rhino gets stuck after running the calculation every time there is a “Convergence not reached” message. What does that even mean? Can the developer place an auto termination when this occurs instead of keeping my Rhino stuck? :sob:

And also, can there please be a progress bar or something? :sob: Having to wait for an indefinite amount of time gives me anxiety…

Pachyderm keeps crashing my document. :sob: :sob: :sob: I don’t understand how a simulation that ran successfully one time keeps crashing down for the other times…
