Disappearing bolts

[Agrippina]

I was just messing with my descr_effect_impacts.txt in an attempt to get my arrows to stay on the field longer, which worked perfectly by increasing the fade_time. I then wanted to do the same for javelins, bolts and ballistas and noticed there was no such entry for those projectiles. Then I checked in-game and noticed none of these leave bolts behind just a puff of dust. My arrows are working fine but has anyone else noticed bolts from other projectiles disappearing when they hit the ground? I’ve tested this in vanilla Kingdoms and M2tW and for the life of me cannot figure out why they are disappearing.

Here is my descr_effect_impacts. Maybe someone could take a look at it for me? I have PB's arrow models installed and I've got everything almost working perfectly. Arrows stay in the ground, flaming arrows are black and burn out after a few seconds and they stick into buildings for a few seconds before fading away. Ballista bolts do the same but only if they are flaming. What I would really like is if I could get crossbow bolts and non-flaming ballista bolts to stay in the ground forever and in buildings for 20 seconds or so. any help would be appreciated thanks!
