Yesterday has sent me a bug on the mod migration worlds when whe used the Zuxelus version of Jammy Furniture.
All items inside the containers jumped on the floor. And a copy still existed in this place in the furniture.
I realized a little fix. For beta you can find a version here: http://www.smeagol-mods.com/dl.php/JF/5.0.0/JammyFurnitureZuxelusCompatibility-1.0.1-1.7.10.jar
For DEV the fix is as follows: https://github.com/GollumTeam/JammyFurniture-Zuxelus-compatibility/commit/70e67e49e905f75fcb30034cae15ade24660045e
Send me if it works well at home.
