Deadsiders, thanks for your patience!
We are aware that at the moment you are facing technical issues such as data non-saving at some servers, lags and other bugs.
We are working hard to allocate the source of these issues. Today we are planning to implement the feature, which will allow us to gather more info on strange servers behaviour and fix the problems ASAP.
Stay in touch.
P.S.
