They changed this recently? I remember my XMR would evolve when I kill people and without explosive rounds

If you change ammo type on the bundle blueprint, you lose the effects (tracer and kill)

No one else notice this?? So basically from now then, you change the ammo type for reactive blueprints you lose the evolve effects?

Earlier today I used one of the Zeus’s bundle— XMR, and I used high velocity ammo, but there were no reactive effect after I killed 10 people. If I remember correct , the blueprint evolve after you kill 10 people and stayed for the whole game. Please tell me it’s a bug

Ami the only one notice there’s no reactive effect when I use different ammo type?
