During a match on Lijiang Tower Garden, the enemy Roadhog’s hook left a persistent chain of hooks across the map. Aside from limiting players’ visibility, it did also seem to impact the game’s performance as the match went on, as more of these hook trails began to litter the map. This effect doesn’t appear on the replay, so I am including an Imgur link so that you can see it: https: //imgur .com/a/RydDIJ1
