Hello! As the title suggests; the game is very weird about downloaded content from the gallery. This leads me to believe that items uploaded to the gallery are glitching, or that the gallery call-back coding is malfunctioning in some way. I have videos to help with explaining this in detail.
ISSUE NUMBER ONE:
Nectar from the gallery fails to initiate correct interaction scripts. This causes sims to T-Pose and the interaction to completely fail, throwing an last-exception. I tried this with Fizzy drinks and Jams and neither had the issue. Not sure why it seems to be explicitly tied to Nectar.
ISSUE NUMBER TWO:
Houses downloaded and placed on lots while on the world map, not on the lot itself, causes the game to no longer function as intended in Build/Buy mode. Deleting, placing, bulldozing, and even changing the rooms Unit Outlines all malfunction completely. If you place a house on a lot while you are actively inside build/buy on said lot the game will not have issues with build/buy mode and all things function as you would expect in normal gameplay.
Videos were recorded while CC & mods were active, however I did also attempt this with all my mods removed, cleared cache, and completely clean and wiped save file (since I actually wondered if it was just my save file being cursed)
I am unsure if it is important; but this issue was recorded on PC, using the EA version of the game as I do not own the Steam version of any DLCs.
Game Version: 1.117.227.1030
An DLCs/Packs: All of them. I own everything in the game.
Anything else to note: I did attempt to see if the issue was somehow related to content with the "Custom Content" tag in Gallery and it did not seem to matter either way.
