Set .avelocity instead of .angles for bezier curves rotation. For one this might be smoother, but the reason is to fix players falling off trains and becoming stuck entities as they rotate (which happens when changing angles / origin directly on push entities). This does not work right yet, but brings the train almost near its correct anagular destination
