Project-GC isn't aware of that TresHntrs has logged GC3762C for some reason. It could be that it was logged the last 1-2 days, maybe a fabricated find even? I could investigate on what date it actually was logged, but that requires some work.
Anyway, I ran a job on TresHntrs profile, and that was their only missing find.
UPDATE: Checked the database. The cache was logged at 2015-02-06 04:57:44. Unsure about the timezone, but PST I think, or close to. Therefore PGC didn't know, the log was too new. The question is, have they actually logged that one. :)
