Greetings Tenno,
It has come to our attention that the Dog Days Glyph in the market was available for sale for both 1 Credit and 20 Platinum. We have changed this item so it is no longer available for Platinum, and will be running a script to refund any players who purchased it for Platinum (while still allowing you to keep the Glyph).
Tenno will still be able to purchase this item for 1 Credit, should they wish!
We will update this thread once the script has finished running.
Thank you!
