Sejuani E bug on Rift Scuttler

Hello everyone,

So I do not have a video for this but I will explain this as best I can.

When I'm clearing rift scuttler on Sejuani, I will get my four stacks on the crab and then use my E to stun it. Sometimes I will E stun the scuttler then go to auto it, but the stun will disappear and clear the 4 stacks, and then I can re-apply the stacks up again (usually if the target get stunned and you auto the stacks will go away and go on an internal cool down). Some thoughts of why this happens is possibly an interaction while rift scuttler is passing through pixel brush, or when it's to close to a wall, or maybe it's about to do its dash. I don't know if using Q or W has an effect on this, and I haven't had the chance to try and re-create this bug.

Has anyone else had this problem?

Cheers, Kasp
