The logistics trait for artillery now seems to work.

[Yogol]

Just so y'all know... the logistics  trait for artillery now works: I just tested this (with version 1.11) with two artillery batteries of 16 24pdr Howitzers: one with the logistics trait and one battery without. The one without the logistic traits ran out of ammunition a lot faster.

Both units had the same command #, same efficiency #, same quality of general and so on.

I did not test the effect of the corps general's logistics trait, I'll leave that to someone else

Yes, both the Corps Strategist perk and the Artillery Logistics perk both work now.  Was noted in the 1.10 update notes.
