I have a multiphase Dymos problem I am trying to optimise. It is not working so far and I think it is because of my sad looking Jacobian, as seen below. All driver values in the problem are scaled such that they are ~ within (0.1, 1), but that does result in a few elements in the Jacobian that have really small magnitudes.

My workflow using Dymos often involves running alot of Dymos optimisations in tandem so I can debug faster (i.e. I can try a bunch of different things at the same time). This has been working until recently. I am using the Spyder IDE and running each slightly different optimisation in its own console. Now, if I get one going in the first console (say (1/A)), open a new console and try to get another going, I get the following error:
