Thanks for the screenshot, that made it easy to reproduce. Fixed in 0.1.14 (Factorio 2.0) / 0.2.14 (Factorio 2.1).
Arig wasn't the problem on its own. Mining Drones Remastered adds its own collision layer to existing containers, including the sushi packers. The Arig hyper packer is created later, so it missed that layer. Factorio refuses an upgrade (turbo → hyper packer) between two boxes with different collision masks, so the game wouldn't load. Extra packer tiers now copy the collision mask from the top vanilla packer.
