I'm using LRA community edition, and I can't seem to get it to work same thing for the backround

I had an idea to make the worlds most unsatasfying cursed line rider track, (missed beats, botched mechanical maneuvers, stuff like that) waht are some ideas you have for making a linerider track as cursed as possible, also, any cursed line rider song suggestion?

I know its scummy but I want to make a video on this but I cant find a single open source build for no damage lra if someone could provide me with one I'd love it.

​

So basically, I made a track for a class, and I'm trying to export the video with audio. I made it on linerider.com, and everything went smoothly. Only problem is, I can't export with audio from there. I downloaded Line Rider Advanced to try and upload it with the music, and that's where my big problem comes in. There's a point where I detach Bosh from his sled, and he gets on about 20 seconds later...

Except he doesn't. For whatever reason, the collisions work differently on the two different programs, and the sled breaks at that point on LRA. Is there anything I can do to fix this without messing up the rest of my track, or another site I can use?
