Making a unit

i bought everything to make an interceptor wing. it says default 40 batteries 410 interceptors, but max it allows me to put is 306 interceptors. i verified i have more than enough available not deployed and enough of everything else needed for the wing.

can you let me know where it was done?
world? country?

we will do the same on the same world and check what happens.

I tried to duplicate this on LU, and while you're right it limits the individual weapons when you make the unit, a quick fix is right after you make the unit you can click on their name then select 'change weapons, ammunition and supplies' and you can change the sliders for how many of each weapon as you desire, and if you have a supply unit (and enough interceptors in your case) the interceptor unit will update to your desired # of batteries/interceptors. The change won't be instant but will be within a game month.
