Industrial Foregoing Version: 1.11.2 (? I am on 1.12.2 but this is the version it shows in the mod config)
TeslaCoreLib Version: 1.12.2-1.0.15
Crashlog (If Any):

Locking the slots on the plant sower does not prevent the sower from consuming the stack but will then prevent items being inserted into the slots.

That's how it works?
