Several Rumble and Sion bugs

I noticed lately a bug when a basic attack of rumble after casting Scrap shield or Flamespitter would not go off in an animation, but would do damage. This is especially noticable when Rumble hits turrets or reaches Overheat.

Secondly, Sion has 2 bugs, one is not technically a bug, but when sion casts his Decimating Strike, the indicator is invisible in some areas, mostly at the inhibitor turrets, because the platform is lifted. The second one is Roar of the slayer does not hit enemies correctly. The animation (or the hitbox) is quite misleading. Plus, kocked up minions hit by the initial roar of the slayer go back as intended, but don't hit anything behind them.
