the new mini client doesnt have any problem at all. they told us so, from their 1st announcement. the new mini client works perfectly without bugs or black screens or lag. its the best version of mini clients. try clearing your cash after you load the game every first time of the day, all days for all the years. if the problem insists, dont use Madara edo tensei. he is too good for the new mini client if you re having him full skill broken. of course the problem will be solved if you stop using him. that's the best solution.
