Regeneration cannot be applied with an amplifier of -1. Please provide the command you used to get the result you did, and steps to reproduce the issue consistently.

Negative amplifiers are read and treated as 0, this was a change mentioned in a change log years ago.
@unknown amplifiers over 128 when saved overflow and become negative.
In any case, duplicate of MC-118857.
Thank you for the clarification. 🙂
