Is this intended functionality ? That it still will read from the roaming folder ?
I seem to have to merge the backups together if I want to reinstate the savegames, because the old (roaming) folder only contains savegames from book one. I guess this functionality was changed in book 2 ? (I don't quite remember). But the older "first version" savegames weren't moved to the new physical location.
Maybe this is something to be concerned about for steamcloud functionality. Does steamcloud remember files from the old and the new dir ?
Yes, it's intended functionality. It's for compatibility reasons.
Yeah, that'd be the easiest thing to do. I manually merged the folders after the update had been rolled out, worked perfectly fine. Just make sure you keep the newest file when there are conflicts. You're right that it was with the release of Book Two that the savegame location was changed.
Well the saves would have been synced to Steam Cloud when they were created. And by default the steam cloud doesn't delete save games when it syncs, so it should all be correctly stored in the cloud. The only exception is if you had cloud syncing disabled when you played the initial Book One, and then later enabled it. Then those old saves wouldn't be backed up.
If you don't want to use the bug report tool included in this build of the game, then yes that's the right place.
