[Gameplay] LeBlanc Mimic Bug - No Effect

When using LeBlanc's W and R in quick succession (and close to each other), the R breaks. It will leave a mark on the ground as usual, but you won't be able to return to it using R and you won't do any damage. The R will go on a normal cool down.

You have to W and then R very soon afterwards and the R needs to be in roughly the same spot as the W (as if you're clearing a minion wave). Doesn't always happen but when it does, it's extremely irritating.
