[FIXED] Build 570 -- Crash when clicking on sonobuoy

[xwraith]

i've had this happen a couple of times when doing the basic training: warship operations scenario

click on a sonobuoy and then the game throws an exception and then wants to quit because of an index being out of range in a list<t> type.

Thanks! This has been fixed for the next release.
