While I am able to make my own creatures with C&C parts and adventures, I can't encounter creatures with C&C parts and in space stage player made adventures with C&C parts are unplayable (it says I don't have the parts needed, even though I do, and says it will replace them but never does so and makes it impossible to complete the mission). I bought the game on Steam recently. If you encountered this problem before and know how to fix it, please let me know how to do so.

Hi @dinomax89
One of the reasons may be, that the EP does not linket on your account. This is a prerequisite to use the online function in Spore. If this not the case, contact a game advisor
