Hotfix 1.3.1

In the last 24 hours since 1.3 was released, a couple of errors have been noted. I have worked hard with several users to isolate the problems. I honestly cannot thank them enough for their patience.

I have updated a few key areas, which should significantly improve stability and hopefully stop some users getting crashes when placing unconnected components and creating wire loops with switches. Circuit Math is very complex and I am always improving the detection of singular matrices or convergence issues

I had managed to miss out a critical multiplication when optimising the Transistor, which was causing convergence issues for the simulation!

All the best
