This is an excellent game, been playing it most of the night. But I've noticed if you try to delete the roller coaster, no matter what you do the game freezes and makes a constant sound. The game won't reset then, even on the R4. None of the other track rides have this problem. Its a pain when it needs to be closed down. I'm not sure if this is a port from the amiga version. Can't remember if the amiga version had this bug as well. Another bug is the handymen, instead of cleaning they end up stuck at the right hand side of the park. To get them working again you have to fire them all, then rehire them.
