Today I experienced at least 20 glitches, but only got a few screenshots. Here they are.
1: Squashed Spiderling Glitch
Spiderlings get squashed on the ground.
2: NPC Question Mark Glitch
You get an NPC mark on your head, and it gets annoying when newbies follow you around, asking, "What mission did you give me?"
3: Forbidden Valley Invisible Ground Glitch
The ground in FV turns invisible, yet you can still walk on it.
