[Extremely Minor] Mass Transmute doesn't unlock achievements

As per the Subject. Transmuting a large amount of materials in 1 hit will only unlock the ‘next’ level of achievement. I transmuted over 800 items in 1 hit and unlocked the 25 achievement, but not the 100, 250 or 500 ones.

Following up by transmuting 3 items individually unlocked the next 3 levels accordingly.
