The Recollection Dissipation - S10-E20
Trivia: When Amy sings "Soft Kitty" in German she more or less translates it literally. The German dubbed version of the show uses completely different lyrics for its rendition instead of just translating the original version.

The Justice League Recombination - S4-E11
Character mistake: Even with Penny and Zack the guys are one man short to be the original JLA because they they don't have the Martian Manhunter. If they used the same costumes in the previous year, they would have been three people short of the original line-up.

The Hot Troll Deviation - S4-E4
Factual error: Howard's claim that characters in World of Warcraft can engage in sexual activities is wrong, also while there is a Bridge of Souls currently in the game, there is no way to get under it.
Suggested correction: I can only assume you have never played on a RP server? ERP is a big thing, some players even make gold from it.

The Mommy Observation - S7-E18
Factual error: Based on the length of Bernadette's skirt and the place she's standing, Stuart could never see under it.

The Mommy Observation - S7-E18
Trivia: The car parked left from Stuart in the future sequence is a BMW i3, which is an actual production car introduced in 2014.

The Large Hadron Collision - S3-E15
Continuity mistake: Penny asks Sheldon if the roommate agreement contains something about girlfriends, which Sheldon dismisses as unrealistic. However, it was revealed in season 2 that there is a cohabitation rider. This was revealed when Sheldon asserted that Leonard's girlfriend, Stephanie, was officially living with them.

The Pancake Batter Anomaly - S1-E11
Factual error: Leonard's myopia is greatly exaggerated in this episode. Even with high myopia he should still be able to navigate his apartment without aid especially after living there for seven years. (00:17:40)

The Zarnecki Incursion - S4-E19
Plot hole: While it would certainly destroy the entire plot of the episode, Sheldon could have simply contacted Blizzard's customer support to get all his stuff back.
Suggested correction: A character not doing something that they theoretically could have isn't a plot hole. It's simply something that didn't occur to them. Regardless, the plot isn't broken because he doesn't do it; in fact, the opposite: it's required that he doesn't for the plot to work. If anything, it's a plot hook.
