Judging by the coordinates these structures only seem to spawn 800-1250 blocks around my spawn point. After that many blocks I don't see these dungeons anymore and all there isn't much left to explore.

I noticed this problem after exploring away from the place I spawned. For some reason there are only dungeons and structures around the place I spawn. I'm not sure if this is intentional or a glitch that I am experiencing. This was a HUGE fun ruiner for me due to the fact the the biggest reason I was excited for this mod pack was because I expected to adventure vast lands and at the same time exploring new structures and places. I've already explored the dungeons around my spawn.
