When a campaign is inactive, everything pauses. The contacts sitting in a 'wait state' will remain in the current wait state until the campaign is active. Time continues to move forward during the 'inactive' state, but the contact will not move out of a wait state until the campaign becomes 'active'. Thus if you have a contact in a 'wait for 3 days' state, and you deactivate the campaign for 4 days, the prospect will remain in the 'wait for 3 days' state. But as soon as you activate the campaign, the prospect will move out of the 'wait for 3 days' state as the prospect has been sitting in that state for more than the specified 3 days.

If you delete a wait state, all contacts in the campaign that are currently in that wait state drop out of the campaign.
