Arrow issues.

Today, I've been struggling with some arrow problems, and decided to use Renderarrow for my custom arrow. Since then I've ran into a serious problem. Whenever I shoot with any bow from my mod and the regular bow, after the arrow hits the ground it appears to fly up into the air, but the entity is actually in its regular spot. This is unaccpetable, and was wondering if anyone had a clue to why this is happening.

 

Below is my custom entity code, set to dissapear when it hits the ground.

Yes this happens for me, too, since I updated to 1.5.1 (Forge 7.7.1.611). I don't know if a later version of Forge provides a fix. I have to test this.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.
