Show merge oddities

We recently merged a cue list from another show into our current file for ease of udating between starlet changes. I noticed last night(first time I've run the console since the merge) that we're missing a bunch of updates that the LD did a couple months ago when he visited. The only thing we merged into the show was the cue list and the couple of position palettes that are Needed for that list and the patch. Any thoughts? Wednesday I'm going to recreate the merge from the same backups that he show was based from to see what happens.

edit: the merge was done on a full boar running version 2.7. Wil try on v3.0 next
