modifications in cv levels ?

• Items may be added to the bundle list late (as its only a single person updating it), but the value will be changed retroactively. If a game is bundled on the 10th, you give it on the 11th and it is added on the 12th, your value would go down.
• If a game has its price dropped permanently, the contribution value for it will also go down.
• Lastly, the occasional bug on Steam, where a games value will go up or down when it shouldn't can also mess with levels.

Look at your PAYDAY™ The Heist: Wolfpack DLC giveaways, it says it gives 0P, so it's currently bugged. It will go back to normal later.
