[2020] Specialization wont get any skill points after patch

As Llama said, this is unfortunately a bug with characters created before 0.7.8. However, what happened is that your character had more skill points than skill levels. So, when the skill leveled up, you would not be granted a point, but you did not lose any points.

If you want to play that old character still, the issue should be resolved after leveling up a few times.
