So I have a redstone machine that the science side of minecraft may know of. It's purpose is to accelerate an enderpearl to stupid speeds as a mean of transportation.

However, the tnt doesn't apply any velocity to the pearls. I have tested this with no plugins, but the bug remained. I have also copied my world to single played and tested it there, where it worked perfectly.
I have also tried to run the server with vanilla-1.14.4.jar - server, and it worked there as well.
