Indeed, it's possible for situations like this to occur right after a major update. Especially when the update brings a new feature(s) to the game. With all games out there, the implementation of new updates always holds some risk. Systems may misbehave, servers could be rocked by instability issues or generally just act up, etc. The devs are here around the clock when ever we release a major update to Top 11 as, clearly, not everything in the game can be tested out internally and show any possible cracks with the same rigorous beating as when millions of players get their hands on it.
We try to catch everything before we release the updates but it's nigh impossible to foretell every single scenario.
It seems that our servers have become slightly unstable recently and thus people are getting disconnected. Some times its the internet fluctuating, and the two different situations can be easily mixed up.
Whether or not it is on our side, make sure you report such instances to the support team, as they need to be informed of such cases.
