Edit: I didn't dream it! If you're being chased by one NPC in stealth mode and another catches you, the first one gives up. Unless you're talking about somewhere else?
"Glitch" at the top was just mapping, but I guess it wasn't reading well, so I adjusted it to something more obvious. Glitch at the bottom was a collision mistake, which has been fixed, thanks for catching it.
I'm assuming with the chase stuff you're referring to the stealth section after losing 3 times. I though I specifically coded some stuff to take into account getting caught while already running, but maybe I dreamed it. I'll take a closer look, but would you mind going into more detail on what you mean by "going left and right"? Do you mean the chasing npc would timeout after a certain amount of time?
