BoE Immortal Game-changing bug

Recently, I was playing SL on BoE. We were fighting for Immortal late game and we lost that fight. We had top keep untouched and our bot keep destroyed by previous immo. Somehow, enemy Immo went bottom, directly to Core, instead of going top to destroy keep. We lost the match, because of a bug.

I saved a replay, and can show it.

this is pretty uncommon and probably the first, simply mail them the replay

Also, shot in the dark, but were any of your healing fountains still up in bot lane?
