Subject says it all.  My build and train buttons are greyed out and it says 'grip of winter disabled ... ' - It's been going on for several turns now.  I can't find anything on the help  :/

EDIT:  Never mind - didn't realize I could dispell it.  
EDIT #2:  Maybe not, all my cities can now add stuff to the queue - but one of the cities isn't doing anything - just has '--' where the number of turns to build is...

EDIT #3:  Looks like some kind of bug, cuz now that I fixed it - the game crashes over and over  :/ 

*needs to find where the report bug post went...*
