I have the season pass for this game on PS4 so I was just adding the usual costume catalog that I do every month for both PS4 and PS3 on the PC site. For some reason, this month's PS3 costume set is automatically added to the download list after adding the PS3 version's catalog. All the DLCs since the release of DOA5 Last Round in February has never been cross buy. Therefore, this should be a bug and can be corrected at any time. I've already downloaded the set to my PS3 and it's working.
Recap, I've already paid for the set for PS4 via season pass but somehow getting it on PS3 as well when adding PS3's costume catalog.
