Iron Bank of Braavos

[Valsharen]

Edit; Turns out this is for another mod.
Leaving the post as a suggestion for content to add though. Feel free to move the post to the appropriate location.

"I read that you can invest money in the iron bank, saw some nice screens of the inside of the bank too. Is this no longer the case?
If so, then is it gonna be added again?
It seems a very odd thing to cut out of the game seeing as the game gets really expensive as you go along unless you use unsullied, which I dont really want to do.
I've tried gaining renown, taking over Braavos, joining the faction. No luck on letting me invest."
