We are able to restore your Sableye, but because it is a requirement for the quest, you must provide a replacement Sableye.
Please provide a screenshot of the System message you receive when releasing a Pokémon, in this case releasing a Sableye, so we can confirm you have provided a replacement. Afterwards, we will restore your original Sableye.
