Maybe i don't understand anything, but which version of OpenXCom you are using?
It's 1.0 Milestone version? Use the latest nightly build and everything will be OK.
I successfully complete mission from your savegame Test.sav.sav, look at your 2 bases, saw 2 billion dollars at balance
Everything goes fine, nothing crashes.
This is a latest nightly build for this moment

https://openxcom.org/git-builds/I don't see any reason at all to use Milestone 1.0 version, because tons of bugs were fixed since June 13, 2014 in nightly builds. It's almost 2 years old, Carl !
