Bought FH4 - Already downloaded on Game Pass - Site is asking me download again?

So I just tried playing it with the internet disconnected and it let me, so I don't know if it's recognising that I own the game or it knows I am still on Game Pass. It's not asking me to download it again anywhere and I don't know what will happen now
when Game Pass runs out? It says in my library on the store site that I own this game. I don't know if I need to download the licence now or not, it's a bit unclear..

The Game Pass version is the same as the standard version. It's probably just needing to download licenses unless you purchased a different edition of the game and it's downloading extras. Game saves are separate from game data. You wont lose your save.

I bought the season pass on the one day it was 50% off and I cant seem to download the new weapon it keeps asking me to pay for it again

I can download gamepass games but when I try to launch them it asks me to buy game pass again. I already have 2 subscriptions for Xbox console which I've paid for

Have you even played the game since the download came out? Stop acting like those of us that downloaded it and already have the season pass are a bunch of morons. I clearly read the "Do not download this from the xbox marketplace" blah blah blah; however,
when I was playing the game and navigating the menus, the pop-up kept coming up saying that new DLC was available. This made me think that the game was recognizing that I already bought a season pass and was asking me to download it. When I saw that it was
1200 points, I misunderstood and thought it was not going to charge me because of the season pass.

I hope you've never made an honest mistake in life. GEEZ
