I sent this email to Zac earlier today regarding this rather devastating bug. I'm a Mahon pledge, so it's not a matter of me having an Empire bias.
I realise this is entirely off kilter etc., but given that there has been no real progress by using the bug report forums, I am hoping you can expedite this issue a little bit, as it'll break PowerPlay beyond belief if it doesn't get fixed immediately.

The problem is very simple to explain - it is currently possible to prepare and expand into system that should be exploited. Not only is this extremely bad for powers that are subject to grinders, but it is also extremely bad if/when it gets used by players out to hurt powers.
This bug should never have happened in the first place, the bug should have been stopped in its tracks the moment it was picked up from the bug report forum, but instead ALD (not my power, btw) is now expanding into a system that is 6 light years from one of their control systems.
Please - if at all possible, walk over to the QA department, grab a senior QA member by the scruff of their neck and threaten them with wet willies until they send it on to a developer to get fixed, and then repeat the wet willy threat with a programmer.
I'll accept having only Bragur fixed as a temporary solution, but the entire bug needs to get stomped out of existence as fast as humanly possible.
If QA or the developers are unsure of what causes the bug, please don't hesitate to have them contact me. While I don't have access to any of the back end of the game, I'm pretty sure I know what causes it to happen.
