I seem to get a quest error with the Iwamoto quest:

I put a "max"  >> T21 (skilled) on Zuikaku, scrapped two T21s, and the quest ist marked as completed, but I can't "finish" it by clicking on it - instead I get the shown error message.

Any hint? What does it say? What can I do?

Tried already from inside and without KC3Kai, but no difference.
