Older Bugs not polled on replication script update
Recently found an issue where a replication script was updated to include an additional platform for replication, but since the bugs had been polled prior to this change, and the bugs hadn't been updated since, they aren't being replicated.
I think a solution would be that when getting the set of bugs to be polled, if the bug's tracker is associated to a replication script that has been updated since the last polling, it gets polled as well, regardless of when it was last updated.
