Heimer ultimate Bug

The Heimer ultimate is broken.

It has been since many patches ago.

When I cast the empowered turret (Ult+Q) then toss the stun grenade, it shows the giant 3-hit grenade hitbox instead of the normal one.

Just try Ult turret, grenade toss, and it shows the 3-stun grenade for me every time.

Got video of it: https://www.twitch.tv/videos/211235682

Can you please fix this it still isn't fixed... it keeps screwing me over in rank. Thank you
