Yorick ultimate bug

Played yorick today went 2/6/0 and when it went to the after screen report it said i did 208k damage, noticed earlier in the game when my ult clone died it did 100k true damage upon death. here are some pictures to help. How to recreate the bug:

1. pick yorick
2. get level 6 and get ultimate
3. ult yourself and get clone
4. kill the clone
5. finish the game and look at the results this has been confirmed on the PBE as well https://gyazo.com/efaa799fc3841a15dbbe4e9311b0fe70 https://gyazo.com/3deefae4ef75576334f06aff68cd78af https://gyazo.com/bb0c9b01b018625951550f66a6020e41
