(I'm playing with Grapple mod v12, on 1.16.5)

Whenever I use a grappling hook and move through a block like Vines, Ladders, or Cobwebs, I only moves as fast as the block will allow me to move. I get slowed down to Minecraft's speed cap. But when I'm done moving through these blocks, the game treats it like I've been falling the entire time I've been slowed down. If I fall through a cobweb for 20 seconds, I take 20 seconds worth of fall damage.

Maybe a good way to fix this is by only ignoring the change in momentum when you're swinging? But when you're dethatched AFTER swinging, the player takes this momentum cap into account?
