A crash at high score screen usually has to do with a bad game.cfg from an earlier or incompatible version (specifically, trying to display a player ship icon that is no longer there). Try removing/renaming the game.cfg in the mod folder and/or the default folder.

I'll take a look at your mod on PC.. Is there a download on the mods subforum?

Is this with missiles in the default game or in a mod? The way the missile trails work is they emit particles at regular intervals, and draw the trail in between. If you're working on a mod and the trails on your missiles seem too angular, you can make them smoother by increasing the firing rate of the particle emitter (or reducing the turn rate of the missile).
