This might seem like a really daft question. However, I am considering buying the full collection of the game (black Friday deal), which includes all the expansions. I'm currently working through the base game of content (I'm doing Cadwells quest) and want to clear everything before moving on. My concern is that if I buy the expansions I'll get a massive influx of additional quests, which will disrupt my current flow. Will this be the case or do I have to manually start the questline through the stories tab? So, in essence until I activate the expansion nothing will change.
Confirmation would be greatly appreciated.
