Very simple bug, you can't throw explosive/smoke grenade through windows. I've linked two screenshots in the additional information, both showing two windows that I encountered this problem with (there may be more).
- Legacy ID
- Look at window.
- Throw grenade at window in a location you'd think it'd go it.
- Run away because you don't want to blow up.
Also, not sure if it's a bug, but throwing a grenade at the windows I've shown in the third screenshot doesn't break them like one would think they would. Also, the third screenshot is another window that grenades seemingly can't go through, like in the original bug I reported.
It should be able to bounce off some of the time; tempered glass is very strong these days.
Nonetheless, I have voted up, as it should be able to go through glass if thrown hard enough.
Window 1: FIXED
Window 2: There is armored glass which is not penetrable by grenades
Window that can't be broken by grenades: This feature request is somewhere mentioned
