I bought the game 6 days ago. I've played 50 hours so far. This is about where traders enter and exit each map. Are those predetermined by each map, or does the AI see where you are starting and THEN decide these points? Also, I don't really understand that map button in the upper right of my screen. I can't interact with it really and I don't see what it's trying to show me. It's just there. Great game, addicted to it for now....

I keep constantly losing my saves when trying to play on GFN, even if I make sure to double check a game saved before exiting. It's getting demoralizing regularly losing progress. Mentioning this here to start off with because I'm unsure if it's the game failing to save games properly, or if there's something on GFN's end going wrong (although I don't typically have this issue with other GFN games)....

1 - Is this game interesting enough to play for hours? 2- are there raids, armies or something that tries to invade and damage your city? 3 - is this just a simple build a city and maintain it game

Yes. Speed 1 for life.

So, I've been having this issue where my commoners are housed literally next door to a tavern with a stocked service counter and their needs will say they have no access to entertainment. Is there something else I need to do?
