I'm using PuppetMaster version 1.0 updated on Oct 15, 2020 and UCC version 2.2.7 updated on Nov 29, 2020.That doesn't sound like you are using the latest version of PuppetMaster.
void OnPuppetRead(float deltaTime) // deltaTime is new.
There isn't a way to download previous versions and I don't keep a archive of the specific version. In this case though it relates to the PuppetMaster integration which I don't think even existed in 2.2.3.Is there a way to downgrade UCC back to Version 2.2.3?
