Game timed out and the game auto-respec’d all my characters…

Has this ever happened to anyone. I was just playing a game like normal and timed out (has happened before). And I joined a new game like normal and I have 139 skill tree points and thought that was weird. Looked at my characters only to find every single one at level 0. Restarted the game/console/everything. Can I do anything or do I have to rebuild all my characters?

Has this happened to anyone? What do I do?
