Extra WL in Isle of Dawn after update?

I am 100% confident that I had collected all of the WL on the map after doing Eden this week (apart from trials), and was at 149 buffs knowing I just need todays shard to get to 150, but as part of my daily run I've just flown through Isle, and to my surprise, there was a WL waiting for me at the top of the hill/steps heading to the temple.

I collected it and am now at 150, definitely hadn't lost any in the last few days, so what's going on?

There has been a bugged WL on the map at Isle for absolute ages, I wonder if it has anything to do with an attempted fix? (E: just checked the nearest map shrine, and the WL indicator for Isle is gone, so this might be it!)

Either way, worth having a look, in case it isn't just me!
