There is the negotiation thing, for example when a user try to adjust the price (from a previously set price), the game disconnects.
The browser platform is more vulnerable to disconnections in certain situations. For example, disconnections have been happening on Day 1 for the past 3 seasons or more, during the period when a good part of the Cup matches start together. I also got several disconnections when the associations matches were just introduced, that is during the first match when this feature started. Since then, I have been using the Android platform for playing association matches.
By the way, I had like a sort of ghost that attended one of my association match when I was not present. This ghost also acted as supporter for the other matches in my association. Why is that? See your inbox. I suspect that this is having a negative effect on my team as my team has been behaving strangely since several cuts-outs a few weeks ago.
I would also like to inform you that it is more likely that the game is messed up. Players don't obey orders as expected; assistant manager has gone ****; matches don't proceed like expected. Strikers don't perform as expected; a lot of chances missed, and they score relatively small amounts of goals. There is a lack of football logic in orders combinations to be used. Transfer market has been **** in terms of 5-star generated players. There have been so many downs lately that I have been 'disgusted' and gutted (and some other users too) and have considered to quit this game several times lately despite just having spent 20 USD.
