This may sound weird, but one of my totems has dissapeared! Is there any way I can get it back?

Were any of the totems the result of banging the gong?

Yes,this one was.

We have discovered that totems created as a result of the gong granting a skill may not be permanent. The villager retains their Esteemed Elder status, but not necessarily their totem. That's probably why you can't find some of your totems.

Is there any way I can get them back?

Unfortunately, there isn't.

That happened to me in my first game thats why I ended up with 51 EES

Thanks. It really freaked me out when I couldn't find it.
