using extra archs I made a engine .5 larger then the normal large one. Now remaking a engine block sets it at 2x scale.
Currently I am hosting was hosting a server remaking the back of Aceis (since I lost the save from server) on this "larger scale".
Extra arches need to be on with those other things else when the server resets. I listed these things on the previous page, which is:
zone events, zone bricks, fence bricks, tile bricks, extra arches bricks, inverted print plates
