Block placement is less reliable in general

In the previous beta, rapidly breaking and replacing a block with another was 100% reliable. Now, in most cases the new block does not result in being placed. 

The place and hold functionality of placing blocks in a line is no longer consistent as well. It is unreliable and will stop placing blocks after around 8 of them despite place button being held down.

These issues make building a lot more tedious and frustrating.
