Explorer's Feast | 探索者的盛宴

we found a world gen bug which is

Error Type: java.lang.NullPointerException: Feature placement

Causing Feature: ResourceKey[minecraft:worldgen/structure / **mtr:stronghold**]

Mod Context: The crashing structure seems to belong to the mod mtr (Moog's Temples Reimagined).

We removed it and removed Seven seas due to some of player dont know how to install Java21.
