Please think again. IF spot is TAKEN 5 min before drop, maybe it doesnt will be treated as a free spot? If spot is free for 1 hour before drop, it should drop there.
Im not saying how it is, just pointing out possible explenations for it not to spawn upon the exact coordinates even if it were free.
What was the closest spot free , other than -55 -19 (that were removed within 5 min from drop) for example?
it doesn't work this way)
TG obviously changed formula for random. but no Winters no CeBAD knew about it. no need to be paranoiac
