T1894_CIRCUIT ERROR

Using example #285, make any changes to the schematic (move a component, for example), then press START SIMULATOR , the "circuit error" sign appears and nothing works, now save it and load it again... now it works. With T1709 it works always.

Tell me please.

Thanks, seems that there is a problem with this configuration, I will try to solve it:
