I use timelines in blueprints, although my project has some C++ parts. Yesterday, all timelines in all blueprints across the project stopped working. I checked the blueprints during runtime and everything works until it gets to the play or reverse node, then nothing (it shows the node playing, but it doesn’t move forward). Everything else seems to be working right. I don’t really know what else data I could give here, this bug baffles me.
