I don't know that I'm affected (since my return I've explored with the new client, even if I've little-to-no interest in wandering about on foot), but I can absolutely and entirely agree that both the time chosen for this split, and the time frame offered for the transfer final warning, are both abjectly poor. Bad official decision making, short-sighted choices and then this thread tops it all off with a few rather unpleasant and casually rude trolls hurling heartless, thoughtless posts in the official thread? No wonder people are feeling justifiably sore about things, and no wonder my ignore list for the forum is getting so long.
I wish those still in 3.8 good luck and bon voyage, and hope they're able to put in a support ticket to resolve their transfer issues. As to FDev - really quite disappointed in the operational decision processes here.
