In past versions, the collision with blocks and clone moving commands worked perfectly, stopping the replace and clone command due to colliding with another block in its path,

now in recent updates, the clone doesn't collide and stop when a block is in its path and destroys every block in its path until it either hits the sky limit or bedrock limit,

I was fond of the collision because I used the commands to run a theatre ingame which had clone elements moving up and down on and off the stage closing curtains and things like that, but since 1.14, that has changed and now doesn't support it and the moving things either break through the Redstone and blocks beneath the object in its path and or all the way up to the sky limit, which is not very practical.

I hope this can be fixed in a future version

Thanks
