If you check the layout the snowflake has, you can see how many bits each part has:

64                                          22     17     12          0
 000000111011000111100001101001000101000000  00001  00000  000000000000
          number of ms since epoch           worker  pid    increment

64                                          22     17     12          0
 000000111011000111100001101001000101000000  00001  00000  000000000000
          number of ms since epoch           worker  pid    increment

As you can see, the increment can be one number between 0 (0b000000000000) and 4095 (0b111111111111). If you pass an increment, you're acknowledging you know what you're doing, as this is an advanced option. As for what the behaviour is when we surpass the range [0, 4095], is completely specific to the implementation, there isn't really a single implementation that's intuitive for everyone. However, now that you point it out, we should likely just mask it into the valid range, otherwise negative values get into the other fields, I have to fix that sweats

And also the cycle should happen at 4096 (>4095 or >=4096), we're accidentally 1 possible increment off, I'll fix that ASAP, ~~will update this message with a link to the PR~~ https://github.com/sapphiredev/utilities/pull/596. At the end, I encountered a lot more bugs. sweats

Fixed in the latest release of the library
