For me it usually seems like its during the morning and only in baseball..Maybe its because we have to click on so many things the server cant handle it..You gotta click on players, then SP, then daily, then owned, then schedule, then add, then ok.
I dont know just throwing ideas out there on what it could be, maybe when you have a bunch of owners on during the morning doing the same thing and clicking on so many things maybe it bogs down the system?
