During my campaign of X-Com Files it turned out that electro-flares, which do not emit light until primed and thrown, start emitting light as soon as they leave the soldier's hand. The upshot of this is that once the soldier does throw, it and everything around it is briefly lit up as the flare travels, allowing the spot/sniper AI to take shots at any thusly revealed soldiers during the enemy turn.
In my opinion this is a bit of an issue, because the point of having primed flares in the first place is to be able to deploy them while remaining concealed in darkness.
Is this something that can be addressed?

Update: This might not be about the flares specifically after all. I did some more poking and found that firing weapons also reveals my soldiers, even if they were unspotted prior. But only if an enemy is hit by the shot.
Edit: I'm told this is intended behavior. I find that very disappointing.
