Hex Ray research unable to complete

Platform: Xbox

Research for Hex Ray gets to 15000 then stalls and is unable to complete.
Have tried on multiple maps to complete the research and it just won't complete like the others.
Cannot get the achievement for completing all research because of this.

Also on Xbox, only 1 research item can be completed before the menu goes blank and you have to exit and reload level to start a new research topic.
