Because Larian is relatively small compared to Bethesda and the game exceeded the already high expectations, it’s a AAA D&D 5e game, which is something people were looking for for a long time. Larian deserves it, and they are actively fixing the game anyway. Bethesda has no excuses to be releasing games that have the types of bugs that they do after having such giant successes like Skyrim. They have the money.
