Very disappointed.
Thanks to previous unannounced maintenances, 4 of my 5 worlds were on the same daily login schedule and lost gems because of this shambles. Yet not a single gem in compensation.
The crystals I couldn't care less about, got more than I know what to do with already so that's scant compensation for the other major loss, losing several rounds of explorer searches with a guaranteed return of goods such as Granite, Titanium and EW and probably some Saltpetre, and on average 6-12 adventure maps plus a pile of map frags, not even acknowledged in this "package", nor the loss of an adv just commenced as the servers went down.
Apart from the two premium days, this is pretty much junk.
Once again, the lack of information was abysmal, the BBs back at HQ could have posted the German news screen to all worlds quite easily, even untranslated it was clear enough to understand by non-german speakers, and I could have got some much needed sleep instead of continually trying to see if game was back up, it was already daylight before we got the news that these servers were going to be abandoned until after the predicted maintenance, even though both German and French versions had been back up and running for many hours by then, yet on here I was locked out of 1 world for nigh on 48 hours, enough time for game actions to freeze.
I should not be expected to hang around dodgy sites like Fakebook in the hope of information appearing there when the game screen is quite capable and more convenient.
