The butler did it! :p
The OP has solved their problem in exactly the way I would have -- MC > Object Stats > Select to Flush. And then the DebugEnabler way as was also mentioned if for some odd reason the MC method fails. Radius Purges are tricky things and sometimes too effective, you wouldn't want to lose a sim or something important like the active plumbob that way so it's best to save(as) first in case something goes wrong.
But just to add some information here, MC Resets on sims, lots and Reset Everything actually rebuild the sims, lots, and objects from the ground up based on the information the game has on them. That's why they are considered much deeper than a testingcheatsenabled resetsim (which really doesn't do much except get sims out of impossible situations) and they do not disturb wishes and opps like the Edit Town evict method does. One should never be afraid to MC Reset a sim, lot, or town. If sims end up looking entirely different or glitch out after such an operation, afraid that means the sim or object was too corrupt to work with at the start.
I run and highly recommend an MC Reset Everything every 6-8 sim weeks or so to keep ongoing games running well. It's intrusive to gameplay, so I try to do this in the middle of the night/wee hours of the morning when I can then send everyone back to bed or whatever they were doing and to minimize the number of inactives at work who would be disturbed. But it does seem to reach some things that Overwatch and ErrorTrap either can't or take much longer to notice, world lot routing seems to be improved after having run one, my games start up and save noticeably faster, etc. Wouldn't want to run one more often than required though, and it can take as long as 10-15 minutes to run depending on one's system, the size of the world and how many sims/objects are in it.
