Game Mechanics: Spell Casting Specializations Reset to 1

[Rmoorenc]

Rindiss 49 Cleric, had Specialize Alteration above skill 50 and rest were sub 50. Used the Cleric GM to raise my sub 50 Specializations to 50 exactly. Next spell cast after training led to a message telling me that only one casting specialization skill could be above 50 and reset ALL of my casting specializations back to skill 1. If using GMs to raise skills would recommend not skilling up beyond 49 to prevent the bug.
