Yeah.
Creatures that begin their turn in the area must succeed at a Will save against your class DC or become confused for 1 round (this is an incapacitation effect). The creature then becomes immune for 24 hours.
You can choose to apply another zone you're able to create, or apply the existing zone again, improving its effects as follows: ... Twisted Dark Zone ignores the temporary immunity of creatures that previously critically succeeded at the save for 1 round.
That is definitely a contradiction and worthy of errata.
Determining the best ruling to use isn't hard though. Trying to argue: "Since the enemy Succeeded at the save, that means that their 24 hour immunity remains intact. If they instead Critically Succeeded, then you could affect them with Zone Overlap."
It just sounds like someone is trying to cheese the system because of a loophole. The enemy gets penalized for getting a critical success result on their save.
And there is a printed RAW rule to cover that type of thing - the Ambiguous Rules rule.
So I would recommend the alternative ruling that Zone Overlap of Twisted Dark Zone for a second time will blanket ignore the 24 hour temporary immunity for 1 round for all targets regardless of what their save result to the original effect was.
