Waystone bug?

SSF

I rarely ever see waystones drop, except from bosses- have all my atlas points in waystones, usually around +90% on the map I'm running, stone cold.

However, I just finished a boss on a map... and, well the map is completed. Right after that I had two waystones drop.

One from a breach, I didn't really kill much, I was trapped in a room for the mostpart.

Then I did an alter and another dropped.

We're talking like 100ish mobs and two dropped, compared to bosses dropping one or two and rarely seeing them otherwise.

Not sure why, but it seemed very odd. Perhaps boss is screwing something up, map completion is messing with the rates. I heavily suspect the +%s aren't even being counted.

I've swapped my atlas passives completely around, in and out of the waystone points- I did notice a difference... but it was very minor. I know that vauge, but this whole thing is kinda vague. lol
