war3ft 2.3.2
the problem is:
after the equpment reincarnation (ankh or orc skill) some times players getting tactical shield so they have both pri weapon and the shield
in that case player unable to buy ammo for primary weapon
and when player switching to the weapon the shield still continue working
so he become invincibil. (nightelf with shield in backpack - crazy mess

but not all the times, i m unable find any correlation so it seems happening randomly.
may this problem was discussed before? then sorry for that
