Without more details we are going to have a hard time finding the issue as we are not seeing any lag with these, even on our underpowered test machines. The daily slots take longer to finish spinning than the normal slots, so if that is what you are referring to then that is not a bug.

i will say same the daily slot is slow like it is pulling on the system trying to work right. i had a big fully loaded gaming computer and some thing is wrong with the daily slot its like it dont want to spin some times it takes along time like sec,s to work .
