As per title. What is the weirdest, most bizarre or incongruous thing that you have experienced during your playthroughs? Feel free to share anything from bugs, glitches to funny coincidences.
Personally, I have seen a lot of funny stuff, but the thing I just witnessed takes the cake.
I am currently going through Watcher's Keep with a low-level party (whose progress I am, by the way, journalling on these forums.) Having just made it to the Final Seal, I send my invisible'd Charname (Blade) to scout the rooms adjacent to the main hall. I decide to open the northeastern gate first... only to find myself swarmed by Devil Shades who could not care less about my invisibility. Unprepared, wounded and spell-depleted, I don't feel particularly thrilled at the prospect of fighting such irritating monsters so I decide to let them have their way with me and reload after my charname dies (lazy gaming, I know.) After a dozen of so *hrrgh*s my charname's portrait finally turns gray and I expect the disintegrating-palm-of-game-over-video to start playing so I can reload the game. Only that it doesn't. My character just lies there, decidedly dead, but I still have full control of my party members. I can access the inventory and stats screens - hell, I can even travel through the portal to the previous level and save the game. Life, it seems, could not care less about the demise of my prodigal bhaalspawn and has decided to go on with its merry little pace.
After five minutes or so of me having my headless party gallop around Amn for the sheer lulz of it, the game catches on and takes me to the long overdue death screen. Damn. I was already considering the possibility of a protagonist-less playthrough.
