While running Calibre Fast XOR with CreateXOR rule files, how calibre is considering LAYOUT BUMP2 value?
In one of my Caibre Fast XOR run, LAYOUT BUMP2 value is taken as 64(How?)
BUMP2 is supposed to be set to a number larger than the highest layer number in the first database. This way, the first database has a unique range of layer numbers, and then the second database eventually has a completely separate range of layer numbers during the run. Is the highest layer number in your first database around 63?
