Immortals players were seen spending the night partying the night before the finals. This led to some of the players being unable to attend the finals on time. The tournament organisers specifically told the players that they had to return back to their seats within an hour for the grand finals to start on time. But the players were simply unable to make it back in time.
Marc Winther announced the same via twitter when it was not possible to get in contact with some players of the roster.
Update from #DHMTL17
After apparently spending the night partying, IMT players showed up late to our match this morning
And again now
