Go creative, fly up 30 meters
Go Survival, die.
Items scatter- no totem of holding created.

Are you using Quark Oddities? I'm just asking because that's a mistake I would make.

I am not using Quark Oddities. And my test environment only had Quark.
In my test environment, I started with just Quark in the mod folder and nothing in the config folders.
Everything else in Quark is working fine (love the huge caves).

You need to have Oddities installed for the Totem of Holding.

Thank you, I wasn't aware it was a separate jar file since it was in the same configuration file. I appreciate the quick feedback!
