Coach loosing ability benefits when coordinator leaves

What

Having coordinators with the same abilities as your coach will remove the benefit when they leave even when the overlap has no benefit. Some not having a benefit might be a glitch as well. 

I also found that outside of the Tactician and the single recruiting hours per week perk, coordinator abilities have no benefit and do not provide additional benefit if overlapping. If I have running back scouting upgrades and my coord has quarterbacks, I don't get a benefit to quarterbacks at all besides additional hours. Similarly, if I have motivator with off season boost and a coord does for the same position, there appears to be no benefit; not even sure the motivator tree works right since its seemingly random regardless of dev trait. Keep seeing elite dev freshman coming off awards not develop at all. 

When 

Coordinator with overlapping abilities leaves to join another team, specifically they left to become a HC. Didn't seem to happen when firing. Didn't appear to fix when hiring someone with same or similar abilities. 

Example

In recruiting you can get ability upgrades for a position to scout quicker and allot more hour per week. Say you hire a coordinator also has those same abilities, you would get no benefit to scouting speed or hours needed to scout fully (possible bug) but you would get the increased hours bump (instead of just 50 -> 60, its 50 -> 70 or higher). When the coordinator leaves it will revert both despite no benefit given to the scouting quickness meaning it once again takes the full amount of time to scout. It does not affect the actual upgrade path so there is no way to get back the quick scouting.

Thankfully found this out the year after winning the second natty and unlocking all archetypes but sort of puts a dent in continuing to maintain a defensive juggernaut when I can't properly scout any defensive players properly.
