Jade Fang Cassiopeia E particle bug

Hi there.

As of the past 2 patches, Cassiopeia's twin fang skill has been bugged. It appears as if the "head" of the particle is missing the texture, whilst the trail that follows it is still in-tact. This causes the normally green skill to have a blue effect on half of it instead. Steps to reproducing the issue.

1. Start any game type/mode (custom/normal/ranked/etc.)
2. Pick Cassiopeia and her Jade Fang skin
3. Go in game and use her E

I have tried the following to alleviate the issue with no success:

• Tested on PBE and live
• Tested on a separate computer
• Repaired my game via the launcher
• Reinstalled League

I've thus come to the conclusion the issue can't be on my end. If anyone has this issue themselves, please let me know and if you've found a way to fix it, that'd be lovely too. I have submitted a ticket to Riot as of yesterday and was told to post it here.

Edit: Also note the hitbox bug (flashing in blue/red occassionally), this is also a bug in patch 4.20 but lots of other people have reported it already.

Thanks
