[GAMEPLAY] WARWICK W (Hunter's Call) cannot be used immediately after R (Infinite Duress)

For the past few days, I've been playing WW and manage to get to Gold on him. However, while playing him, I noticed a strange bug. This bug prevents the player from using W (Hunter's Call) for a few seconds after the use of R (Infinite Duress). I am unsure of how long this bug lasts for, but other skills such as Q (Hungering Strike) does work. After a certain delay, W is able to be used again.

I play on the NA server, and have been only using Warwick with the hyena skin. I have not tested other skins or the classic. I have tested warwick on multiple days and each day the same bug occurs.

I am unsure if this bug only occurs for me, or if everyone is affected.

Just wanted to bring this to your attention for anyone who may play warwick. The way I bypass this is to use W before engages, slightly annoying, but still playable.

Thanks for reading and have a good day!
