Channeling tridents on lightning rods can create lag if on a fast clock

When you throw some Channeling tridents on a lighting rod connected to a sideways facing sticky piston with a clock on the other side (to make the tridents strike the lightning rod over and over), the game lags like crazy. on my iPad, it only takes 3 tridents to make the game unplayable. On Windows 10, it takes more like 8. On my iPad, it crashes with around 10. On Windows 10, it crashes with 15-20. I do not know if this is related to RenderDragon.
