If you are having problems with the Three-in-One, such as your buildings resetting to level 0 or plans not showing up, try this:
1. Load up the first save from before you installed the Three-in-One.
2. Let your character sit for a few minutes. Sim Settlements runs code each time you start the game to check which building plans are available.
3. Go to a Commercial plot or Advanced Industrial plot and use Choose Building plan, if Commercial - look for New U or PA Service Center, if Advanced Industrial - look for Lumber Yard or Oil Well.
4. If those plans are missing, wait a few more minutes and check again.
5. If they continue to be missing, then something in your save file is preventing the start-up code from running to confirm that you do in fact have the IR and RotC files and you'll need to revert to the individual mods.
