It has come to my attention sometimes Sims may have a routing issue e.g.
Sims can't pick up items, stomps their feet or waves like something is wrong, won't route to a certain spot or action cancels out. Like at the junkyard for example.
While testing this issue (on a lot I made, that has spawners) it was found it was more to do with lots that have spawners on them placed from the library and/or rotated, rather than a specific save file.
The spawners have a chance to double or triple, or quadruple depending on how many times it needs to be rotated.
This can be fixed by editing the lot, to remove the extra duplicated/triplicated Spawners via buydebug.
To get rid of those pesky extra spawners:
1. Ctrl-Shift-C together to bring up the cheat console.
2. Type in testingcheatsenabled on and then type in buydebug on.
3. Shift-click on lot and select either buy or build on this lot.

For those hard to delete items, press Ctrl-Shift together, while having mouse over item and select Delete it.
