Unknown Prefab causing crashes

[Satchs Boogie]

I had taken a break from the game for a little while after the Campus update. When I came back the game would no longer load and after several failed attempts at solving the problem, I eventually just unsubscribed from everything and started over.

I've been adding mods and now assets only a few at a time. One of the mods I use, Ploppable Rico, is known to have some issues and was the last mod I enabled before moving on to assets. I've now got around 30 assets (mainly houses) in the game and again I've started getting crashes. In the Crash Report I've found a lot of files with the following:

Unknown prefab: .1434153549%002EBlack Angus Steakhouse_Data_Data [Serialization]

There are quite a lot of these for different assets but what interesting is I haven't subscribed to these assets....yet. They are all former assets I had subscribed to before unsubscribing from everything and starting fresh.

I'm assuming all the data has been left behind from my previous subscriptions but how do I get rid of it all without dumping the assets/mods I've just subscribed to. Do I need to start all over again?

Missing buildings/props don't usually cause crashes, it will probably be something else.
