With the development of the large features coming we have a new grid system which is why we won’t look at old grid system bugs. There have been a few performance improvements on the new system and we’ll make a few more before deployment, for example walls should not cause any issues once the new system goes ready for experimental.
I have own Airport ceo long time this game came a long ways! I’m just waiting to jump back in again when the new features comes out!! Great work Developers!
