Guild Influence
Login influence has never worked “correctly” — assuming we even know what ‘correctly’ means in this case. If all your characters represent the same guild, you can get anywhere from 0 to 80 influence on any given day, but rarely the same amount. This has been true since I started testing, about a month after launch. (There are some variations once you have multiple people logging in, which makes tracking even more complicated.)
As for event-generated influence, maybe you can offer some specific examples (and screens) of the amount of influence you expected and received, plus the circumstances. It could be bugging out, or it could be that expectations don’t match the mechanic. (It’s confusing at best and we don’t have any official confirmation of how things are supposed to work.)
