I thought I fixed every way the button got stuck but nope, you've found another haha thanks.
As for the trains, aside from getting stuck on corners the other features haven't been added to any build yet, that'll come soon.
Thanks for the help!
The building connection I believe is because bulldoze mode is bugged and doesn't pick the right spots, I'll get onto that one.
As for the flying random things, I'll make sure to add a delay because it does just fly back and forth, and I'm aware of the dodgy buttons, I'll make sure to look into all of them very soon.
Appreciate the feedback!
