Hey there, thank you for reporting this!
Could you please provide a list of the mods you’re currently using, which might cause this issue?
Also, Disclaimer: The mods haven’t been created by the dev team themselves, therefore they can cause bugs, glitches and crashes in the game, especially after official updates. During this Early Access version of the game, it is very risky to use mods, so feel free to disable them at any point to get the best version of the game possible atm 
There are a lot of mods, so I can’t name them all. I tried to turn off some of them and with several city changing worked and with several didn’t. I will pin screenshots with mods with which city changing doesn’t work.
Hello Andy!
I suspect this might be caused by mods made with the “Wizard” which gives other issues such as gray hair glitch etc. Are the mods highlighted the ones causing you this issue? Try after disabling all mods by the same authors, if the game goes back to normal, I would recomend contacting them via Curseforge!
Let me know
Hello! No, the issue is caused by clothes mods from different authors. Gray hair glitch I didn’t observe. The problem is only with city changing.
I see! Try contacting the mod authors to see if they might know what the issue could be, or ask them if they created their mods using the wizard. Best of luck finding a solution!
Hello, I’ve just been made aware of this forum and this. I will reach out the inzoi team directly. I do not use wizard.. Thank you to everyone who has had patience during these exciting new updates that have added some complex new issues for us modders. We truly are doing our best. Modding is a full time jobs work between curating meshes, weight painting, texturing, thumbnails, fighting the buggy modkit we’ve been provided and then constant updates. I appreciate all of the support and feedback and I’ll post here when I have a solid solution or correspondence from the inzoi team. A quick solution on my end would be to remove all old mods until there is a solution to this. This is what I did for Sims in the past. In the meantime for your curiousity and if I don’t respond before they dol I’d keep eyes open from the Inzoi team directly for updates on what this issue is. Thanks so much.
I just realized this is old, I apologize! I was sent this forum from a follower and the other thread is not available to reply to. Edit: it was I’m just new here sorry guys </3 ;(
Just seen this post but just wanted to add, I have been so confused as to why snow doesn’t show up in the game for SO long and after seeing this and removing all the mods from the game, the snow finally appears! Just need to figure out which mods are conflicting now…
