Otherwise though if it's only a few actions (3, prob 4 at the most) and the impression is the whole thing was a bit of an accident then i'd be inclined to roll the action back and treat the other bets as out of turn.
Opens the game up to a whole load more angle shooting.
For example, you have a marginal hand UTG you can now simply cover your cards with your hands, hope UTG+1 doesn't notice, see how the action goes and then call it back when you know if it's going to be limped behind you.
That's where some common sense comes into it. If the dealer reports that the player has done something like this then we can kill the hand.
