What you were expecting to happen, and what actually happened:
Mail Subject (reward summary) Legendary Task to say what was received in an abridged version. It could have said “11 traitstones” but it said “11 minor water traitstones”. The actual reward had 5 runics and 6 arcanes.
How often does this happen? When did it begin happening?
Didn’t check for repetition. Looks like a visual bug, that’s all.
Steps to make it happen again
Possibly complete LTs and hope for it to happen again.
