Camille Bug

I was playing camille in LotPK (Legend of Poro King) and learned that if an enemy camille ults you, if you've hit a poro and recast it then you become untargetable. Now this would be normal if you stopped at camille's ult walls...and you do, but you remain untargetable b/c it thinks you're still traveling to the poro target, and i could move while untargetable for a couple of seconds after camille's ult was over, but then I became retargetable after the couple of seconds. This could easily be exploited in LotPK and ARAM if there is an enemy camille unless fixed.
