Odd new error / bug? Can't open ammo crates??

[meade95 0]

All of a sudden my guys can no longer just walk up and open an ammo crate? I use to walk up to crate, the option of "rearm at US. Weapons" message would be within my scroll. and I wold left click it. Now, it only appears quickly and when I click it, my guy simply knees down but the crate does not open. (No pop up screen). If I then click the "gear" scroll option the crate will open but then if I pick a weapon that say has a gernade option. When I select that weapon grenades are not automatically fitted with the weapon (which has always been the case before).

Any ideas?? I have not DL any new mods or made any adjustments...
