Rollbacked trades are missing rollback information.

[Devx09]

Hello, I have noticed that sometimes TF2 trades are being rollbacked by Steam and even though they have "tradeID", are rollbacked (can't be resent with identical same IDs, returns 26 when trying) and got state "6" (canceled) don't have any rollback information when I call getExchangeDetails.
Is this a known issue or something new that needs fixing?

My guess is that the v12.2.2 update that fixed corrupt data on normal trade offers doesn't consider rollback data and when it's corrupt - no data gets returned.
(Just a guess at this moment)
