Short description of error
A prop that's put into place via a copy transform bone constraint disappears until you hide and then unhide the collection it's in.
Exact steps for others to reproduce the error
Open up /scenes/01-opening/01_050_A/01_050_A.28.blend
...notice how the staff prop that should be in the character's left hand is missing...
In the outliner, hide the collection "Staff meshes"
In the outliner, unhide the collection "Staff meshes"
...notice how not the staff prop appears in the character's left hand...

This file actually exhibits a bad memory use-after-free error in debug builds with ASAN enabled... That's for @fclem or @atmind

@Jeroen-Bakker for you too :)

Regarding original report issue, this is likely some missing update trigger somewhere... Adding a new mesh to, or moving an existing one into, the
Staff meshes
collection also makes the staff appear again. @Sergey or @brecht may be interested to investigate too?This issue was referenced by

This happens due to the
OBGRP-Staff_proxy
object matrix not being evaluated in time forOBRIG-staff
to use it.Changed status from 'Open' to: 'Resolved'
