Can you see a button on the right side of the Moment select screen for Step 3? Clicking that will show Baxter's five Moments. If the DLC is properly installed, the Moments will be playable. If not, they'll be locked. If they are locked, maybe try updating the base game with a new version and adding the DLC to that. Or make sure the rpa file is in the right folder.

Okay so, for some reason I loaded one of my saves from step 2, and changed Cove to crush instead of love. And then baxters route was unlocked thank god. So when that happened, I saved that, but then when I go to my original save which I'm dating Cove, Baxters route is locked there still. Does it matter if I play and finish Baxters route step 3 in a seperate save, then load up the save where I was originally playing and where i'm dating Cove where I had done all his moments in Step 3, even if baxter is locked still? Basically I'm just wondering, the main story where I'm in love with Cove on one save, and then on baxters route on a seperate save, but NOT in love with cove, how does it affect or change the story and or relationships with everyone, if that makes sense? Thank you and sorry again (｡•́︿•̀｡)
