I seem to have discovered the issue, and it seems it could be a possible bug.
What seems to have happened: I changed my minimum payout threshold to 0.015 BTC, after the balance had already reached a point higher than that. As such, it didn't seem to "trigger' the payout as the threshold had been bumped lower than the current BTC balance. Once I changed the threshold to something higher than the BTC balance on eligius, once it reached that amount it successfully "triggered" the payout into the queue system.
So, it would appear changing the minumun threshold for payout "jumped" over the trigger, and resetting to an amount yet to be attained it successfully triggered when hitting that point.
The My Eligius options do not take effect immediately, as is written on the options page.
In the case of dropping your minimum payout below your balance in an effort to trigger a payout... I purposely deprioritize such changes for an addtional amount of time (in the code).
Eligius is not a bank. Eligius does not have any manual withdraw feature for many reasons, mostly security related. I do not want people abusing the My Eligius settings regularly to that effect, hence the delay in such a change taking effect being an effort to curb such behavior.
