Are you using a mod that replaces the vanilla stronghold?

Opened issue with Better Stronghold mod. Also, latest Greater Eye Mod has a null check and will display a message that the Stronghold was replaced.

YUNG-GANG/YUNGs-Better-Strongholds#34

FYI, nothing I can do when mods remove/replace vanilla structures. It is up to YUNG's to do something, if anything.

The author of BetterStrongHolds is not planning to fix the problem, so nothing can be done on my end.
