I find it rather ridiculous that a teammate, either because they are called away and do not quit, are too new to know what to do, or, most often, are complete asses, can stop an entire team from advancing in an episode by not standing on a shard pad. These are the pads that typically act as marshaling locations for a team before some important event, like the fight with Geoff in The Algorithm.
I propose a simple fix: If one teammate has stood on a shard pad for at least one minute, regardless of what the rest of the team is doing, the next event is triggered. This means that at worst one player can slow you down for one minute. One minute is also long enough that it should not cause an issue where one teammate rushes ahead without waiting, as there are not many places where it is realistic to get such a large lead on your team and essentially abandon them. Also, I’d rather have that issue than be prevented entirely from advancing.
