I am getting a script call fail too with either the Modern Mettalic Illuminated Display Case or the S1M5-4 Test Tube Pedestal (or any other GtW retail pedestal objects) at the SientistLab venue. I had a player made lot from the Gallery there for years in my longtime save file, which is available at the Gallery: MarmeldadArt "FutureSim Labs".
Recently the game deletes those objects when I visit that Lab in that save file. I never saved then, because I am unable to place the objects again and I don't like to have an unfinished lot in my favoured save file. When placing the lot freshly again from the Gallery, then it's placed but exactly those GtW pretail pedestrals sometimes delete with no info at all (the small pop up telling you that objects were deleted does not come up). The lot from MarmeladArt contains many GtW pedestrals as decorative objects on the roof and those two mentioned in the beginning on the ground floor. (Note: I got rid of the pedestails on the roof in my save file, so I do not have that much info on them like on the special two mentioned in the beginning, but when placing the lot freshly from the gallery again, most of the roof ones were deleted too.)
I was able to make the game throwing a LastException which might be interesting for the devs. The Problem seems to be within the GameObject Tuning for those GtW objects, especially with the small business states. Mind you this is happening in an unmodded and in modded versions of my game. If it helps, here is the full LastException:

Edit: Sorry I needed to reproduce the LastException as the former one was from my modded Sims 4 folder. This one is from my unmodded one.
