I have my objects "Enemy Assault Army" deactivated in the hierarchy. I have the activation track set to activate them a few seconds into the clip. (Refer screenshot 1) But... when i press play the Enemy army self activates (Refer Screenshot 2) .... The timeline isn't even triggered to play yet...what am i doing wrong?
Try turning the preview mode off in the timeline editor, then disabling the GameObject. It sounds like the scene value is defaulted to on. In the editor, the timeline in the window puts all values it affects into preview, which means their values aren't saved.
