I have only added the message for the few quests I know had this issue surrounding the big event in v0.6. I'm sure there are other quests where there can be long pauses and there is no way to progress until you get a notification saying you can. If anyone can point me to such cases, specifically at which step in the quest log it happens, I'd be grateful for the help.Good move!
This game is actually quite hard, compared to other games at this website. Some quests are really extended in time and you can progress them only if you do something totally unrelated (or it seems so) in another quest. Such hints that you can't do anything at the moment will be certainly helpul.
