I've just uploaded GH2 v0.627 to SourceForge. This is meant to be the stable release before I get all freaky on the game balance. Here are the hilights:
Plots Updated: The convoy defense missions should be possible at all renown levels! The city defense patrol bug has been fixed! The old buggy Bounty Hunt mission has been restructured from the ground up! Several deadends (mostly related to the Easy Money path) have been fixed!
Bugs Fixed: Sets should be unpacked before getting inserted into containers. All gear recovered from battlefields will be marked as salvage. Lancemates can learn talents as well as skills from plot events.
Mechanics More Useful: A spaceport's main mechanic will always be factionless (not applicable to campaigns already in progress). All service NPCs who offer mecha repair will also buy mecha.
That's about it. Try it out and let me know if you run into any problems.
