Are Serb lamps bugged for civic pride

[Silkt]

I am lvl 32 in civic pride, I was at Sir Coth at 7PM when he said "its getting dark" no one had lit the lamps between the 7PM game time and me lighting them as they are mostly visible, so I would of seen someone ahead of me in the circle around the well, I lit over 20 lamps but only got 3 ticks of xp. I was not the person that filled them.

Prior to taking a break not long after Fae Realm was introduced, I would of got xp for every lamp, has a recent patch intentionally or unintentionally changed something?

I just went through and lit all the lamps in Serbule on my alt. I got civic pride for some but not others. One trend i noticed was that it was the lamps that were empty or near empty that gave no xp. The lamps that were fuller gave xp.

My hypothesis is that turning the lamp on during the day (which some people do to make room for more fuel) causes the lamp to give no xp when turned on at night.
