I'd guess it's more likely the didn't tighten it rather than over tightened.

Per you comment on the original post, the oil had not been checked in several years, and the side vent was very tight. You did not mention that the clutches were replaced by a dealer and the gear box serviced. I assume that this leak is new since servicing. It seems that the box was overfilled slightly by the dealer per your comments on the level. A slight drip when removing the plug is normal, 8-16 oz is over filled.
Here is a way to look for a crack. After replacing the side cap with Teflon tape applied, clean the area with solvent. Note, some solvents may remove the paint. Brake cleaner being one of them. The purpose is to remove any oil before step 2.
Step 2: Spray the area with Gold Bond foot powder. Try for an heavy, but even coat of white dust. A crack should show up as a wet line radiating from the edge of the plug hole as the oil seeps through. This is similar to die penetrate inspection.
