Hello, fellow goblin :)
I'm confident the bugs, Goblins -> Centre hall and Pregnant like buttons are fixed in the upcoming update, which I will upload in about one week.
And, I like your AND/OR suggestion, so if everything will go smoothly, I will add it in the update too :)
Also, I have spent some time on the connection buttons to work a bit better, but it's still not perfect unfortunately.
Regarding your corridor and two way bridge suggestion, I am afraid that both of these would be quite difficult features to add with the way I made my code. These two might actually be something that I will have to add in the sequel, if I make one.
