Currently my Romance Festival won't despawn causing massive issues when other festivals overlap. I believe the Nerd festival takes place at the same venue. Since the Romance items are still all in place, the Nerd stuff just gets crammed in there willy nilly making a lot of the items inaccessible. (Especially the stall vendors)
Does anyone have a cheat that can reset the lot or festivals? I tried to edit the area, but the only editable building is the Karaoke Bar and doesn't allow me to select the open park area items.
In the mean time, I'm going to wait till the next Romance festival and try to attend the entire event in hopes it triggers the despawn. Will update when that happens.
