We are losing half our entropy by doing this, but it is necessary to

preserve reverse compatibility. If the top half of our current 64 bit

seeds ever starts getting used, existing worlds will break due to a

|

different hash outcome and no way to differentiate between versions.
|

A solution could be to add a new bit to designate that the top half of

the seed value should be used, essentially a 1-bit version code, but

|
this would require increasing the total size of a seed to 9 bytes (yuck)

It's probably okay if this never gets fixed. 4.2 billion possibilities
