Javlok Alt-fire will lock animations, restrict movement, and allow extreme speed.

[rainy]

Patch 24.7.1

Bug: Retrieving a thrown Javlok too quickly can put the frame in a state where you can only walk in a single direction, sliding will skip the slide and teleport you forward, while bugging animations. This can be undone in-mission by performing a charged throw and reloading uninterrupted or swapping weapons.

Steps to reproduce:

1. Throw the Javlok closely, with any charge.
2. Pick up the Javlok quickly before the long throwing animation ends. Sliding during this step makes it more reliable.
3. Hold W while rapidly pressing Shift to move the frame short distances forward at extreme speeds. 

Result: The quick movement will interrupt the reload, allowing the player to maintain the state and traverse long distances in a short time, and can preserve the speed if launched off a ledge. Some actions are stuck in the Javlok's throwing animation during this, even after reloading, the primary fire will repeat the same animation.
