I've noticed skirmishers {infantry at least} won't skirmish when reloading .

I know this has been the T.W. standard for at least the last 2 previous games , but given how long it takes to reload a musket it is epic silly to the point it should be called a bug .
If they're being charged , they don't have time to finish loading anyway {as melee interupts the cycle , death also interupts it} thus the "feature" is not only useless , but it also is basically bugging the skirmish feature {which is only really usefull if your unit can actually use its' missile weapon} to the point of being also useless .

For what it's worth , the unit I discovered this with was the French Light Infantry {whom got squashed by charging British Line Infantry} .
