When I send a mining ship to autopilot to an asteroid, if the ship doesn't arrive at it's destination in the next turn, it won't start working on the asteroid automatically. It needs to be moved off and onto the asteroid again to work.
I've witnessed this bug playing as both Custom Race and the Altarians. I figure it happens regardless of faction.
Both times I was using the default game settings from installing the game, with the exception of difficulty being set to normal.
I've also noticed, although this may be intentional, that I am allowed to rename planets that are not under my control. The Torian homeworld now exists under the name of 'butts lol'.
