from the sounds of it, every time you hail the buff bot it generates a random code that is logged somewhere. the table the code is logged into eventually fills up and doesnt work correctly until emptied. so i guess it is kinda like a milestone =p
Saylinks are are a hacked way of item links from live. It's a regenerated hex code that is simply sent to a table via the database to recall easier. When these random saylink code's are being generated by the buff bot it fills another row in the table each time. Usually the source code for EQemu is only able to scroll through so many rows or entries of a table that it is told to query from. For example: items that we have dumped from 13th floor reach up to ID increments of close to 120,000, and 120k is exactly what's defined in the source code to be max. I have made the mistake myself of adding ID's beyond this number, causing items not to load period. Saylinks would likely do the same thing.
