I'm not angry or saying its the fault of the author for this bug but I spent 3 days (Or arguably more) building a nether fortress farm to farm wither skeleton skulls. Using other mods the bounding box was visible but it extends all the way to the bedrock roof.

The issue with this mod is that it makes farms pretty much impossible to build by just using the bounding box and nether bricks. Which is a huge killer for this mods usability for a regular play-through.

Solution: Greatly decrease the size of the outside bounding box of the fortress, and make sure mobs can actually spawn inside this bounding box. As seen in another bug post, it doesn't seem like the outer bounding box dictates whether or not mobs can spawn.

Unfortunate :/ .

I'm not sure why this might be the case, as I'm using the exact same type of mob spawning rules for structures as the vanilla fortress. Maybe could be an issue with my API's structure generator improperly modifying the bounding box? Regardless, this unfortunately won't be an easy bug for me to fix. Sorry for it impacting your playthrough.

The same Problem is affecting the play-trough of me and my friends.
