Unable to open cues/palettes

So I've got some issues with a show.

It was originally programmed on a Hog 4 in 1.2.0, but has been through all versions since and is now on a Roadhog 4 with v2.3.0
Certain positions and cuelists will not open.

I either hit "position" "open", or "cue"cue", or "cue" xx "open", and the object does not open and I get error message "Unable to retrieve object for id 112 from fixtures array"

It's extremely frustrating...


P.S just tried it in H4PC, same error message.
