Transfiguration bugs

Title: Transfiguration Reduced Existing Strength Affix and Made Item Unmodifiable

I believe there may be a bug with the transfiguration system.

I upgraded my shield to 25 Quality before performing a standard transfiguration without a Tuning Prism.

Before transfiguration:

  • +200 Strength
  • 25 Quality

After transfiguration:

  • +194 Strength
  • 25 Quality
  • Item became Unmodifiable

The transfiguration appears to have replaced my existing Strength affix with the exact same affix at a lower value. I lost 6 Strength and received no improvement.

I have also experienced several other transfigurations on fully upgraded items that produced no noticeable improvement but still made the items Unmodifiable.

I have before-and-after screenshots showing the Strength reduction.

Please investigate whether transfiguration is incorrectly rerolling existing affixes to lower values or failing to apply an improvement.
