I collected over 50 of the terra and sea crystals respectively and I had a charged balance crystal and an uncharged balance crystal. After the event I did not receive the orbs. Now in the halloween event, my husband has a counter that counts his jack o lanterns and I don't. Am I going to miss another reward?

No, the counter button is a beta trial, only a few players have it. You should still get the rewards if you collect enough jack olanterns. You just need to check your storage for them instead. Once you have enough, you should get the reward next time you log in.
