subcircuits with 2-terminal voltage sources don't work about circuitjs1 HOT 3 OPEN

There's a bug in the simulator that causes the first circuit to not work. It's throwing an exception, which is handled and ignored, so that's why nothing happens.

The problem is the 2-terminal voltage source. It doesn't work in subcircuits because of a bug.

You can work around the issue by doing the following:

1. create a ground node like so: https://www.falstad.com/circuit/circuitjs.html?ctz=CQAgjCAMB0l3BWcMBMcUHYMGZIA4UA2ATmIxAUgoqoQFMBaMMAKADMQAWbFEXTioSr8+vMNCQxIKFgCdBVMBkIKQKPHijJ4LAO6qetIXzwDIe1es2EUAq1BZpy3XiJdqEKgQDUAlgDtHSHIbOw0QUI8vEG8AewBXABcWADcuYhVsU3SVJRUqKk5aLQKJC04MkwFPYWzzfQrc5VU8hwbKrIF3TocnLh4q-tdsaIBxABMWAHM1DF5bKkx5uZKWIA

2. select everything except the ground

3. create subcircuit

Thank you very much for your rapid and efficient reply. Everything works now.
So I must remember : all circuits yielding a subcircuit must contain a ground, even if, when making the subcircuit, we choose not to include the ground in the subcircuit.
I also must remember to use 1-terminal voltage sources in subcircuits.
All the best, and thank you for your great app !

reopening this so I remember to fix the bug
