tested this with a low level character in handiness....he went from level 5 to level 6 without ever completing the repair. If I let him continue...he will max out his skill and never repair that speaker.
You can recreate this with any household. You just have to wait for a neon light, speaker or stereo to break after doing the upgrades on them. I think Fixum Wiring is the culprit. The sims have no issue with plumping repairs
This is most likely caused by seasons, and rain going through somehow. I noticed the basement will display raining even if its not raining just because the ground is wet. There is two work arounds I have come up with raise the foundation a level above the ground so you don't get ground weather. 2 Anything that is broken and not fixable should have a replace your still keep all your upgrades.
