Can anyone Explain why my actors are disappearing after bouncing?

[Slayer]

Perhaps I misunderstand the "Projectile" flag, but can anyone explain why my "glass shards" bounce normally, but when they lose momentum, right before they stop bouncing, they actually disappear? I actually want them to hang around for a bit.

I've deleted it, but before I had a Delay() and then A_Remove to despawn all glass shards. (to clean up actor count). This worked well, but after implementing the bouncing, they just disappear way before the delay timer ever got done.

I think BounceType Doom actors go to their death state when their velocity hits zero. The default actor death state is just to disappear. You could put a custom death state in there or try Hexen bounce.
