Today I played a round on ramiel as ARF and after around 1 hour this happend:
As you can see we had two known (where really there) and one unknown (wasnt able to spawn there, no idea if there was a cache or not)
The unknown stayed till rounds end.
I have never seen that, but from wat I recall if there is one "known" and one "unknown", then u CAN spawn at the "unknown"... now 3 caches at the same time I have no idea nor seen it before
