This is a very interesting issue ....

If you take out an empty honey comb, it triggers a filled hone comb until the last slot if filled.

The honey isn't continuing on because of the bias metric. When it gets stuck, the bias is 17 and the randomness is random 17 must be 0.

here is the issue ...

if (bias != 0 && curCombs < maxCombs) {

shouldFill only becomes true when there is a bias if there are less combs than the max. So, once it fills up the slots, it wll never be true.
