The old
BagReseedfunction updates the seed with a non-bijective function and takes on only 2^16 values, so the cycle lengths are often on the order of 2^8, sometimes much shorter. It's not rare to see the exact same queues over and over during PC practice sessions.The new one updates the seed with a full-period LCG of period 2^31, which should eliminate short cycles entirely. This change is not backwards-compatible: states from older versions of four-tris cannot be loaded after this change, and vice versa.
