-Cutlasses and Vampires are now immune to tractor beams, since they are completely helpless when held in that fashion.
Completely immune? How about have them simply slowed down (50%? 75%?) while being affected by a tractor beam instead?
Yep, completely immune. Same as a lot of starships and also raiders. They are just really useless when slowed down or stopped, because that not only reduces their movement, but also their attack ability (since that is so inextricably tied to movement for them). On the bright side, this works in your favor, too -- when sending a group of cutlasses through an enemy wormhole, previously they were useless if there were tractor beams there. Now they'll clean up (or at least have a chance).
-The way that unit data is sent to the AI thread now requires no string concatenation, which should prevent the rare OutOfMemory exceptions that a few players with extra-high amounts of RAM were getting.
Since when is 8G RAM "extra-high"? 
Cheers!
Ha -- well, it's above the 32-bit addressable space, so I consider it extra-high for the moment. I'm sure that opinion will change before too many years have passed. I have 4GB in my Q6600 desktop, and I never reach it even with dozens of programs open at once, many of which (like Visual Studio and Photoshop) are quite memory-heavy.
