Bug Fixes
- GIC: Fixed bug when loading a *.gic file in which a two-winding transformer's bus did not exist it could cause an exception.
- Transient Stability: A recent patch was added to catch non-linear governor gains where either All GV or All PGV values are zero and default them to ignore the non-linear gain block. This was good to catch, but we were also catching as an error when all Gv AND Pgv are zero which has always mean to ignore the gain block. New check will properly ignore when both sets of values are zero and not report an error.
