Unfortunately there are bugs in BD, but in general game play the only ones i have come across often, were the monsters in walls, the "Item 67776" instead of showing bread or whatever, and the getting stuck in a wall a couple of times, the other bugs i have seen once or twice, is clicking on a locked entrance (especially the cave behind the ranaar temple) and going through the locked entrance into the cave, some quests not initialising as they should (but if you play the game liniar, this hardly ever happens, it mostly happens when you have the solution before you ask the question... and there are others....
Mostly people with either uncommon hardware configurations, tons of other programs installed (it affects the common windows libraries and thus the way windows cope with the game), or people like me who do things backwards
You are lucky if you dont run into bugs, but i think you have run into more bugs than what you noticed... most people dont notice the rock in the forest that is marked Item 67776.. or similar stuff that we just dont notice, until we know about it.
