So I have found a problem that causes strongholds not to spawn while using this mod. I tested multiple things and only when removing this mod will strongholds spawn!

This is the only message in my logs relating to both strongholds and also traverse:

[12:40:25] [Worker-Main-8/ERROR]: Couldn't load tag minecraft:has_structure/stronghold as it is missing following references: traverse:wooded_island (from Traverse)

This should be resolved in the 5.1.0 beta we just released.
