Dear Users,


Today i had this problem after run the staking:

Someone had this type of problem and already know a way to fix?

probably python is using integer division and because in it the quotient is rounded down... it generate the error?

probably the solution is simpler..

looking forward to know about you guys!

very very thanks!
