Again, another old issue but it was naïvely treated. The current Lyn we have still has this problem. Furthermore, it's not just with Sonic. It's with every single opponent that throws her. Again, it's most certainly a PSA issue of her file. Her thrown animations in the PSA need to be tweaked to avoid this issue.
Edit: On the other hand; her Thrown animations are really wonky and G-mod style (lol). This could be a factor that causes the unprecedented boundary bubble. Reanimate them, polish them and that bubble should go away than wasting time on analyzing on mere PSA grounds.
Update: As I was playtesting, I'm noticing that some stages that have a ledge, and Lyn being grabbed and thrown near the ledges with sufficient amount of damage causes the unprecedented boundary bubble glitch. This may indicate something more than just her animation.
