Issue: Oxygen Reduction Rate correctly applies when first gaining the skill and its further upgrades, but after death the Oxygen Reduction Rate does not reduce oxygen consumption rate anymore despite the skill still being listed under the Skill Stat Bonuses in the character sheet.
Testing Method: With the first application of the skills including all upgrades, character can last under water for at least 3+ minutes before suffocation. After death, character begins suffocating after 1 minute. After removal of the skill through respec, character will still begin suffocating after 1 minute.
