Hi !
I'm using AWE (3.9.4) + WE (7.2.12) + Paper (1.19.2 # 127) + BetterStructures (1.3.1).
This plugin use worldedit to generate structures during world generation. It paste schematics to populated minecraft worlds.
When using AWE, chest inside structures are empty, and spawn signs aren't removed,
But when removing AWE, chest are fullfilled and signs are removed. So i think there is a little trouble between AWE and BetterStructures.
Thank you in advance for your support
