Contributor Level changed?

There are several possibilities why a level drop happens:

1.) The base price of a game you gave away on Steam changed. Your contribution value will change accordingly.

2.) A game you gavae away is in a publisher bundle that reported a wrong price due to a sale. (see e.g. here)

3.) A game you gave away was added to the bundle list with a "bundle date" preceding the date of the giveaway you created. As only one support member working on the bundle list, this might happen.

Edit: That kind of level changes happen all the time. I think I had a too high level due to 2.) or lost a level due to 1.) and 2.) about 15 times until now. That is nothing to worry about.

Understund! Thank you very much for your help!

I lost about $100 in CV some time in the last few days. No idea why. Usually it's due to a price change on Steam, which is effectively retroactive on SG.
