That dialogue glitch was interesting. I think either the there are limits to dialogue with what now would appear to be digital constructs (which puts into question the reality of the human side of the setting as a whole, knowing the monsters can exit portals), or the system is limiting the knowledge available for the player at this stage.
That is one example of it occurring, yes, but similarities with the image presented here and your source end at the 100% tip. Everything else has been modded to bait that rage.
