Hello there, In one of my servers I was testing a command and the outcome wasn't even close to what it was supposed to be. I'm building a theme park with my friend and the command was to lift the minecart slowly and tilt at the same time. The command was "/execute as @e[type=minecart] at @s if block ~ ~-1.125 ~ stone_stairs[facing=east] run tp @s ~.125 ~.125 ~ 0 45" The minecart is supposed to tilt 45 degrees but instead it tilts 90 degrees. I tried to change the rotation and it just turned the minecart to face south.
