	//what that caused was that the next valid bank inherited the current valid banks FULL fire delay. since he used the Weapon_info struct that has
	// no information / member that stores the next valids banks remaning fire_wait delay.
	//
	//what he should have done was to check of the next valid bank had any fire delay that had elapsed, if it had elapsed, 
	//then it would have no firedelay. and then add 250 ms of delay. in effect, this way there is no penalty if there is any firedelay remaning in
