** In patch 1.025 you fixed an ammo pools bug (3rd line of patch notes).
"- Fixed a bug where you would lose ammo swapping weapons in the current loadout when the ammo pool was full."
The bug is back, again, and was back before this patch. This occurs with all weapons. This will occur after a complete resupply at an ammo cache.
It can and frequently does happen when swapping weapons, swapping loadouts, changing locations via jump points, porting to a friend in a different phase or logging in.
The total ammo available will be the 'Ammo in Weapon + Ammo in Reserve = Total Available #'
Example using a Wolfhound with a +12 shot extended mag: Pistol ammo is supposed to be:
"Loaded Weapon + Reserve = Total Available". --> 24 + 250 = 274.
The bug will result in:
"Loaded Wolfhound (24) + Reserve (226) = Total Available (250)
** There are times (during a siege is most critical and most noticed) when one is low or out of ammo, and will access an ammo cache, get a complete resupply of ammo for the primary weapon of the equipped loadout, and ZERO ammo for the secondary weapon. On occasion if one has swapped loadouts during a siege and expended all ammo for different weapons pools, those weapons pool ammo quantities will not be replenished either, or at best PARTIALLY replenished.
NOTE: I've also gotten '198' as an ammo replenishment for a wolfhound or flaregun as primary weapon in my active loadout during a siege. Thats just nuts... It's not like I left some of the ammo on the counter at the depot when I ran out.
