If you activate 4 totems withouth having Thor constructed the game get stuck, the dialog is the same and commander talks about throwing Thor to the black hole (while thats imposible becouse there isnt any Thor), also the game get stuck when Thor should be going to the Black hole.
Another minnor glich is that if you have a weapon flying when the blakc hole is opened it wont be sucked in (this one is only a visual bug).
It took me 47:36 to end the last map in this alternative way to see a posible alternative ending and I was a little disapointed :P.
You need download a patch :)
In v0314 all is fine.
Yeah, just patch the latest version and it will fix all of your problems.
