I've run into this problem on at least two different scenarios. Sometimes, when a unit has a Horse SFT, this SFT will not regain readiness, dropping the overall AP's for the unit. Notice in the screenshot, where all of the SFT's - except the horse - in the unit are at 100 readiness. This has happened in GPW and in Tom's WaW scenario. The strange thing is that it doesn't happen with all units, but only on some. In each of the units that is affected, the readiness is maxed at 60 for the afflicted horse, and the AP of the unit is dropped down to around 77 to 78.
