Gameplay Bug walk through the krugg camp wall

I was Tahm Kench Support and tried helping the jungler with the first camp (Kruggs, we were blue side). I was rightclicking onto the border of the wall and walkable ground (in order to make Tahm Kench goin mad twitching from one direction to the other). As far as NORMAL. but as the kruggs spawned i was somehow able to walk through the wall right behind the camp. That couldve killed me in case the enemies wouldve been invading.

I managed to reproduce it once but only once luckily. i was rightclicking at the spot between the Tree Trunk on the backside and the small tree that was on the left of the trunk. then i held the rightclick and after a few seconds of twitching around you would normally go the normal path behind the camp. but if the camp spawns in this few seconds it happens.
