This bug involves a poster that was released in an older AC scratch almost two months ago. The specific poster that causes the bug is: Episode 3 Poster B. After placing the poster in your personal quarters, any attempt made to re-enter your personal quarters will result in an infinite loading screen. This result will occur with any player attempting to enter your personal quarters. There has been a fix made on PC ONLY by private users. NOT EVEN the developers have attempted to fix this issue which has persisted for almost two months on both console and PC.
