You have already been given an answer. We are starting to implement the engine on a wider scale, this is not a voluntary situation and in the very near future every player will have the updated version. If you believe technical issues caused losses then you are free to contact our Support with the details:

That was a non-answer. You arbitrarily chose players who are doomed to suffer and those who are not. 

"every player will have the updated version" ------ those who join after the "bugs" dealt with will lose nothing. You do not have any legitimate argument here. As for getting rid of flashplayer, are you suggesting that we turn it off and on every 3 hours? Remember, our comps are doing something but plarium. 

If it is proven that the large majority of those you subjected to losses are non-coiners - that might create a legal problem.
