Orianna Bug

I have played a few games of orianna of late and have noticed a few wierd bugs... 2 infact. 1st one is if you ball someone (shield) as they are about to leave aka panth ult or tp your ball will come back to you but it will be invisible... 2nd is if you throw your ball then w and walk out of its range super fast it will do the same (note: i have only had this happen once) but the ball is still usable eg to throw and combo or ball other people... its just not visible on orianna.
