Summary	0000546: GETOWNER flag is not working as intended
Description	https://zdoom.org/wiki/Actor_flags#GETOWNER so far I tried this flag, it simply isn't doing what says on the tin - the trail actor keeps targeting the projectile - unless I am missing something stupid here. Tried with gzdoom g2.4.0, and gzdoom-x64-2.5pre-268-gca4888e.
Steps To Reproduce	Here's a testing rocket launcher I made. It fires rockets that spawn exploding trails, which aren't supposed to harm the player, yet they still do. On regular fire, it fires a decorate-based rocket, also summons particles that warp to target pointer. They are clearly still warping to the projectile instead of the player. The alt-fire sends a zscript-based rocket, in case this was supposed to only work with zscript.
Tags	No tags attached.

A_Explode tends not to behave properly unless it's specifically coming from a missile or monster. You're using the SXF_ORIGINATOR flag. When used, it uses the actual spawning actor instead of transferring truly from the shooter. Try removing that.

EDIT: Not that it should really matter, cause it should work without it as well, so far I tried on this, corrected case.
