when a gem drops the sound dropitem.waw plays changeing dropitem.waw will make you mad at some point trust me, archers drop arrows you hear gems and start looking for one,same for scrolls and ores.
Must be another way in the conquer files there is a line like drop gem play :what ever sound i want after i name it dropgem.waw
there is a dropgem.waw sound but its never used i think TQ messed up can we fix that ?
