School bus problems

@TokusaShi  I don't think those four mods would directly affect whether the bus shows up.  Buzzler made one that allows players to disable carpools and the school bus by choice, and there may be other mods that disable the bus by default.  (I'm not totally sure.)  There are a few things you can try to fix the one save though, in order from least to most intrusive:

• Delete and replace the school in Edit Town.  This will reset all students' grades to C and kick all adults out of the Education career.  If you don't want that to happen, place another school somewhere else first, delete and replace the original, and then remove the second one.
• You could also just place a new school and get rid of the original, or leave both in place if the original is really too crowded every morning.  (To force already enrolled students to go to the new school, you'd have to delete the original and place both at the same time in Edit Town.)
• Use NRaas DebugEnabler, if you're interested in adding it, to Fix Homeworld.  Click on City Hall and select NRaas > DE > Options > Sim > Fix Homeworld.
• Use MasterController to reset the town: click on City Hall and select NRaas > MC > Town Options > Reset Everything.
• Evict your household in Edit Town and immediately put the sims back in their house.  They'll keep their jobs and relationships but lose their promised wishes and opportunities.
• Same as above, except after you evict them, save the house to the bin, bulldoze the lot, and replace it with its bin copy before moving them back in.

Be sure to use "save as" to rename the save, so you have a backup, before each test.  Quit to desktop and delete the five cache files before reloading and testing.
