I have been away from Sins for a while, just got the 1.05 patch and started a game.

I parked a fleet in a wormhole well that I wanted to defend, half my fleet kept chasing the enemy through the wormhole. No matter what I did or where I put the fleet in the well ships would keep jumping through the wormhole. That fleet got decimated as the AI just killed off the stupid ships that jumped then  it just jumped in and finished off the rest! Why the hell wont my ships stay in the gravity well I park them in! This is frustrating as hell and frankly makes the game unenjoyable to play. This was never an issue before, I also had another issue where I jumped a fleet from planet to planet, when I got there I saw I was majorly outnumbered so I jumped my fleet back, the stupid fleet jumped back and then turned right around and jumped right back, lost the whole fleet as the ships in it just kept jumping back and fourth between the two planets WTF!

EDIT and what happened to my z-axis control!!!
