EDIT: This also happens with Sims not just lots, but in the case of downloading Sims from our own offline gallery it crashes to desktop.
I'm on the latest patch but already since the Patch before the current one I'm getting lastUIExceptions when opening lots on the Gallery, when I'm starting the game in offline mode. This is happening only when in OFFLINE mode, and only since the change to the Gallery that has changed the UI a lot.
I assume some lots are trying to pull information when displaying, that is now causing an Exception with the new UI when not being online.
For me this is happening to nearly every second lot in my gallery, most of the lots are saved from the online gallery, so it could have to do with comments on them or items used or some kind if detail, but I could not find the pattern for why some are doing it and some not. The "Cannot access a property or method of a null object reference. at widgets.Exchange.Detail.controls.TabContentPanel::DetailTabSectionedContentPanelBase/RequestItemsForBundle()" sounds a bit like there are items from a pack that are not getting recognised maybe when offline?
I have tested this without mods and don't even need to go into a save file, I can reproduce this from the Main Menu quite fast. It happens to a lot of lots, but not to all lots, I can give some examples below:
Preparation steps:
- While online, go into the public gallery and save following few lots to your personal gallery, these here are some examples that reproduce it each time (once we are offline) :
- "Whole Foods Grocery Store" by Kells8994
- "clothing store" by flaviagabis
"Shopping Centre - Mall" by Korbyn77
Repro steps:
- Go offline and start the game
- On main menu, open the Gallery (your personal one, given you are offline)
- Klick on to open any of the above 3 lots (and many more if you want to try your own as well) and you will get a lastUIException, and from now on will have troubles opening anything in the gallery, the lots in the gallery are now unresponsive when tapping on them to open

This is how it looks like when i try to open them, they don't render the "information" and i stop being able to interact:
And these are some of the lots, as described above:
