## About The Pull Request How did I miss how `COMSIG_SHELL_ATTACH_CIRCUIT` was handled? ## Why It's Good For The Game Makes a circuit shell actually do what I claim it does. Fixes #90786 ## Changelog 🆑 fix: Fixes assembly shells not taking power from machines/mechs/borgs instead of needing a cell when attached to such things. Did you know this was supposed to be a feature, but didn't work for who-knows-how-long? /🆑
