It is my first time to create an event for my guild but I have found a problem of which I am seeking for advice to solve it:
When I switch the event into "playing" mode, matches are automatically generated. However, only the players who joined prior to the switch can have matches, players who join late will not have unless I re-start the stage again. This, however, will reset all the matches which might be unfair to the early-joining players. I wonder if there is any solution to this problem, or I am just unfamiliar with the set up function? Please help if you know how. Thanks.
That's easy, just be assertive and don't accept late entrants.
There is no way to get around it. When making an event you should get all applications before the event starts. If you really want to accept late entrants you need to reset it.
