Adobe Productions Media Offline even after Reattaching Proxies

This issue is as follows:

• I have two separate projects within an Adobe Production
• In Project A I have a multicam clip, and the footage inside the multicam clip is offline
• I paste the multicam clip onto a sequence in Project B - the footage remains offline
• I reattach proxies to the footage in Project A, making the footage in the multicam online when I load it into the source monitor
• Back in Project B, the footage within the multicam remains offline in my sequence.

Even when I match frame on the multicam clip in the sequence to load it in my source monitor, it still appears offline. Even if I duplicate the original multicam clip in Project A and paste this duplicate onto a sequence in Project B, it still appears offline.

My workaround has been to duplicate the source clips in Project A, add those to a new multicam, and use that new multicam in Project B.

It feels like the issue is that Project B is somehow "remembering" that those clips are offline, so when they are used in Project B they appear offline regardless of their true status.

On a side note, Adobe in all its consistency also works the other way:

• I have a multicam clip in Project A, and the footage within the multicam is online
• I add the multicam clip to a sequence in Project B, everything is still online
• I offline the footage within Project A. When I open the multicam clip in Project A in my source monitor, everything is offline
• In Project B, the multicam footage remains online, and can playback even though it's not linked to anything at its source
