Swain Q range bug [Gameplay]

1.) When casting Swain's q you cannot see the tether range as either the caster or fellow summoner. This bug was quite debilitating in my most recent ranked game. Unable to see the range (relied solely on memory) made it neigh impossible to effectively combo my q with my w in and out of lane phase. Furthermore, the q dropped off completely in some cases when it was used to kill 1 minion, and never reattached to another target.

2.) To reconstruct this bug simply cast 'q' in or out of a minion wave.

P.S.: Do I get my LP back? Diamond is hard enough...
