Also, 1 hour to take 7% of hull seems reasonable to me, depending on how many ships were shooting it. I don't think it was GRN as we hadn't yet decided to take action on it, we're waiting until we and the rest of the Gallic HC finish making a station construction regulation to post before we enforce it.
If the Brimstone did indeed go boom, I highly suggest the owners abstain from rebuilding it for a few days. That way you can then get proper permission from the government to construct it. If you do want it to go up sooner, contact me on Skype or PMs (If Skype, it'll be 5 hours before a response) and we can work out a temporary waiver for construction allowing you to have the base while we continue deliberating on regulatory conditions.
