Lag spikes in game.

I was experimenting with the new stair types and when I placed them down I started to receive minor lag spikes. I removed stairs, moved around some more. I created a new flat world and continued experimenting lag spikes. There's no evidence to link the lag to the stairs but in game lag spikes where experienced after I had spawned in a new block. I will continue to see if this is a resolvable error or possible client side.
