Doesn't this happen to every weapon since the beta? Also, does this happen to you while you use any other weapon?

No they "fixed" it 2 times already as far as I know and there was a post by one of the devs afterwards which explained the causality in detail. It's not something that can be easily fixed I think. Something along the lines of the server disregards your reload update as spam/packetloss or whatever. You'd have to look for yourself though...

It mostly happens after shooting and reloading several times. Like there is a small spawn, you shoot 7 bullets - reload - next spawn, you shoot 14 bullets - reload - no spawn, you have a little time and switch to your X-bow to check on your ammo-status - and now when switching back to your SCAR-H, and this happens almost every time, you loose up to 7 bullets on your SCAR-H

BTW i did not experience the bug on other weapons perks so far.


EDIT 26.05.2016: Also appears on other perks with different loadouts independent of X-bow usage but it seems that when playing Commando the dissapearance of ammo is more severe than on the other perks, especially on the SCAR-H.

To sum it up:

1. This seems to happen because of ServerSyncReload() (KFWeapon.uc).
2. This happen only online because ServerSyncReload() in online thingy.
3. ServerSyncReload() sets the current ammo counter:

AmmoCount[0] = Min(AmmoCount[0] + ClientReloadAmount, MagazineCapacity[0]);

MagazineCapacity[0] surely never exceed its normal value (so no subtractions on dry reload) and SpareAmmoCount always subtracted properly and only once per reload, so it is

AmmoCount[0] + ClientReloadAmount

where it gets messed up.
4. It not always subtracts 1 round from magazine. On high ping servers i had up to -16 rounds subtracted from 45-rounds Bullpup.
5. Ammo subtraction does not seem to happen exactly on reload completion, it likely happen after the replication of AmmoCount when server being notified about client reloading and then through attempting to sync the ammo pools while client have its weapon switched (you shoot some bullets from already half-empty mag, switch to other weapons and remaining ammo pool being subtracted, so does this meant that server not being notified about reload canceling?).
