Strictly speaking may not be a bug, but it's something I've just confirmed for myself, although was pretty sure about previously and doesn't work like I think it should.

The daily loyalty and stat gained for each day you log in.

If you are idle when midnight passes (or, I assume, active) the loyalty gain occurs when midnight passes. When you refresh/resume play you get the calender telling you that you have gained the stats, however in actuality you may have received them some time ago.

Should the stat and loyalty gain not occur when you're notified of it? i.e. when you've resumed play and actually displayed activity within that calender day?

Spoilers:

Its in the main config file, this means that many many things can possibly give you your loyalty.

Not sure if that's agreement that it shouldn't work like that, or if it's meant to be?

Its telling you where it affects it, precisely where it should work is another matter entirely

This has been resolved.
