Spoiler warning, I'm gonna be talking about one of the last areas of the campaign.

So I was playing the campaign with my bro. We got 3 people sitting in Dingo Keep, opened the door and got in the spaceship that took us to this green area with the exploding cubes. Can't remember the name.

We cleared the first "room". Up until you have to dodge some timed lasers to press a button that lets you destroy this big cube that looks kinda like a computer.

We destroyed the computer thing and kept going. There's this button that both players have to press together and opens a door in front on you but closes the one behind you.It takes you to an area with 3 turrets an a few guys with robes.
We killed the wizards but could not progress past that room or go back. We searched every inch. All we could do was die at the same time to respawn outside the room.

After a few tries, to see if we missed something we tried quitting and reloading. Now the button that originally opened one door and closed another behind us, didn't open the door. It just closed the one behind us...
If we waited a bit the button would pop up again and the door behind us would open. But we could no longer access the next area.

So we decided to go back to the Dingo Keep via the teleporter and try to get in the room with the spaceship again to see what happened. Entering that room made the game crash to desktop.

Otherwise, great campaign. Cheers to the devs. I'm really curious to see what was going on here, maybe we just missed something.
