I'm not exactly sure what happened but my latest save seems already fine with it. There's no more weird stuff happening except if I load that save again from the previous update.
Saving on the new version seems to fixed things. As for the Event Menu, I simply clicked Return on the menu to back out of pause and to make the button come back. Seems inconvenient though I can deal with it just fine, but hoping this could get fixed for the future updates.
Edit:
No scratch that weird pause bug seem to occur whenever the Event Menu button is present, but just as I said from the strikethrough text above its just something to do with Relationship menu. I just need to make the Event Menu disappear (by not clicking Return while inside the Relationship Menu) and play the game as normal and only clicking Return when I need to look at the list.
Again, inconvenient and cumbersome but I can deal with it. Hoping this gets fixed for the next update though.
