BMP 1 firing sound loop

[anantdeathhawk]

On Bamyan Coop, i was using a BMP-1 and the sound of the its canon fire loops even before it has reloaded for a subsequent shot,only if you keep the fire button pressed after firing once.
,It isn't a big deal though,could be solved by just pressing the fire button once.This happens only with AP and HEAT shell.
