I'm receiving the error Peripheral 'back' is no longer attached randomly when push/pulling modules, from the Neural interface on myself.
I'm not able to replicate the error with peripherals.

1. Get a Neural interface, Neural connector, Introspection module, and Daylight Sensor (Or another module)
2. Put the Neural interface in your helmet slot, Introspection module into the Neural connector, and Daylight Sensor in hotbar slot 1.
3. Open a lua prompt in the Neural connector
4. Execute peripheral.find("neuralInterface").getInventory().pushItems('equipment.6', 1) (Might take a few attempts)
5. Observe error
