Ah, ok, glad to hear you have a TWDU map. (Otherwise I imagine there would be IP issues)
Hard to imagine what the problem is since you say “TWDU” (and not TWD (rule 1.a.))
I’d try making a new private version on the creator portal, then when TWDU publishing officially opens try submitting it. (Maybe the island moderators / appeal reviewers will be educated to the fact that TWDU is now ok to say at that point)
