Playing as Ancients, I moved a fleet led by Moros into the Gas Nebula. Whenever I hit the "Begin" button it just resets the loading bar. No matter how many times I click, it just reloads the bar. Autosave also brings me to the same screen, so technically its a game-breaking bug.
That usually happens when the map file isn't included correctly. I'll investigate.
Can you reproduce this issue with the current patch 2.1.1?
