The same bug that was affecting Cryoclasm has also been impacting the three afformentioned sources of Slide improvements. If the player is already sprinting at the time they gain the benefits of Amplified, Speed Boost, or Peacekeepers then they do not get the improved slide until they first stop sprinting and start sprinting again. This is especially noticeable with Speed Boost because it can literally only be obtained through sprinting and massively impacts melee focused playstyles on Arc subclasses by making them move slower when trying to approach enemies that are still shooting at the player.
