The "connection lost" thing is a bit misleading; it just means the user interface lost "connection" to the back-end game engine. This simply means the game crashed, and the UI doesn't know what to do now.

There are some mods on the Steam workshop that enhance skirmish and increase stability, though unless the mod creators specifically put the mod on some external host like ModDB, those are only accessible through Steam...
