Unable to drag puppets to timeline

[Desmond2407799411r5]

Hey, I've been using Cha. Animator for a few weeks now. But randomly tonight, for some reason I am now unable to drag a puppet from the Project Tab to the Timeline. I am able to use the puppets already in the timeline, but unable to add new ones... Thanks.

Can you post a screenshot or screen recording of this happening? What happens if you try drag one of the puppets that's already in the Timeline?
