I play on a server with 2 friends and we use the beta version. There seemed to be two updates yesterday and since then my ships (captain controlled ships) started acting strangely. We warped into a sector and immediately two of my ships started firing at my third ship, before I could tell them to stop they destroyed it.
Next time we warped into a sector one of the ships then refused to follow any orders and was "stuck" in it's position. I had to take the ship apart and rebuild it to get it to move.
Lastly we warped into a sector with a lot of enemies. The ship refused to warp out of the sector and got destroyed. I know this ships hyperdrive was recharged as all my ships are built to the same specification.
Didn't have any of these issues until updates yesterday.
