I think more of a business logistics issue. 20% of activity transferred off G-land in a week, which means by month's end the server may become Wayfinder due to self-catalysis. Ignore the transfer page, that only tracks characters as they are caught logging in and out. Activity is what matters.
The economic modeling of allowing this to continue two more weeks is non-linear and complex, so I would have halted it to determine the long term business viability and plan to limit the impact of a global rollback or server mergers if determined to become necessary.
Something like this is planned and calculated for months, not allowed to occur as a by-product of a bug fix.
