[#3520] Mission Updated sound bug

[AkrionXxarr]

It seems that if you have a mission step that requires an inventory item and you transfer a bunch of different inventory items at once (e.g. in/out of HQ storage or buying/selling to a trader) then the "Mission Updated" sound effect plays multiple times on the same frame (presumably once per unique inventory item transferred) which can generate an absurdly loud sound (headphone warning if you try this).

Here's a save with me at my HQ's trader. You should be able to replicate the bug by trading a bunch of different inventory items at the same time (or going to the personal storage and transferring a bunch at the same time): Save Game
