Missing platinum key in Tactical Tower New?

[ererqion]

I just played through Tactical Tower New and came up short towards the end of the "Dream" section when I found I had one fewer platinum key than I needed. This surprised me, because I have been able to complete the tower previously using the same tactics.
Checking through the floors, I notice that on 16F there's a tile with no items on it one space to the left of the clear tile. The pattern on the tile makes it seem as though a platinum key should be there, but it doesn't appear.
Was it removed in a recent update? If so, was this intended behavior?

Sorry, one PlatinumKey is missing due to our mistake.
We will fix it in an update in a few days.

Thanks for letting me know. I'll look forward to the update, but I understand if it takes a little while, as I imagine you're busy right now working on Chapter 7.

It will be updated the day after tomorrow along with the new stages that will be included in the Main package, but since it is always delayed, we are releasing the revised files on Twitter.
(It will be properly fixed later in an update.)

Thank you! I apologize that you went out of your way to make this update available early. Hopefully in a month or so I'll be able to buy Chapter 7 and catch up on the updates to which you are devoting the majority of your time.
