Potential Wax Contribution Firelight Ruby exploit

Unless I missed something obvious, the five Odd Globs of Wax donation to Middles in Gundargaz in the Ringing Deeps for a Firelight Ruby doesn’t seem to be deducting the items from my inventory, essentially allowing for free Firelight Rubies.

I have 14 Odd Globs of Wax in my bags, and I’ve donated to raise the percentage up to test it, but I still have 14 Odd Globs of Wax. I was able to get two Firelight Rubies, which should have cost much more than 14.

I am level 85 and have not finished the War Within campaign if that is a factor.

Glad I’m not the only one to run into this.

I’ve long since completed the campaign for The War Within. I thought I miss counted how much I actually had turned in. But when I went to verify the count after each turn in, the stack was indeed not shrinking. I started my turn in with 110 in bags (with 2 in my personal bank) and still have 110 after getting 2 Fireflight Rubies. I moved the Odd Glob of Wax stack to a different slot to see if the stack just wasn’t updating, but it still shows 110.
