apologies for bug report if this is (for some weird reason) intended
this group of treasure troves
(assuming GT is correct)
according to GT has no sub groups/only these 4 spawns, and sometimes (somewhat frequent) it’s not spawning at all
this is same session/1 run
as you can see no trove in either of the 4 spots
since i’m pretty regularly getting the trove to spawn in 3/4 places i’m sorta guessing it’s the northern most trove that might be bugging out?
*pretty sure i’ve seen the trove spawn in the north point before, but don’t remember if i saw it after 9.6 too
this happens on both my GoG and Steam install 9.6 of the game, so it’s unrelated to any of the potential modifications present in the screenshots (steam install)
(also, if this is indeed a “working as intended”, why? 
only treasure trove group that acts this way it seems 
)
