As a football manager, I may ask a player to play as a left corner back, but maybe due to injuries, I will demand the player to play a right back. So it would be nice, before the player "reaches" his 40 or 50 skill points, to be able to cancel progress and start all over again with a new skill. currently, if you try to play someone who is still learning how to be a "AML" for example, the game will show you a red exclamation mark, which means the player does not know what to do there, even if the player has 49 out of the 50 required points. So that means, according to the game, the player will not learn a new position until he completes the full training of 40 or 50 points.

Your example says, to forget "AB" which is not what I mean here. Based on your example, I want the player to forget C, before it's marked as complete and move on to a new skill. If the player already has a skill associated to them, that should not change. I don't see any issues canceling a skill that is still in progress.

Cheers!
