Inconsistent and frustrating Stealth XP

[dan.io.wal]

I'm frustrated. Honestly. I just did three or four spy missions in a row using the following loadout.

Banshee, Paris Prime, Sonicor, Atterax

Due to my use of the shade sentinel, I was able to sneak up on several enemies from behind, getting the prompt to perform a stealth finisher on them. After doing so, I got neither the stealth bonus nor the stealth bonus XP. Was something changed that was not announced in the developer notes? I don't normally do long survival runs, and stealth spy runs are how I level my weapons, mostly due to the bonuses gained when you don't screw up when collecting the data

Please fix this? This has been going on for a while now in almost every mission I do.

There is an old mechanic in place where enemies don't provide stealth xp if they were killed within five seconds of spawning; this was to stop an exploit of abusing some crappy spawn mechanics of the time. The spawning has been fixed, but the mechanic is still there, even though it is no longer needed.
