• Pawns won't lean around corners to throw grenades 90 degrees around them. The tiles at the grenade's max range (~12) are indicated as valid targets, but if you target them, the pawn just continually aims without throwing. EDIT: Upon further testing, they'll happily throw frag grenades around the corner, but won't throw flashbangs. No idea why this is the case.
• If you throw around a corner at less than maximum range, even if it's only a tile or two, the grenade travels very slowly--presumably, this is the pawn lobbing the grenade high and it sailing in an arc.
  I suspect something's not quite right with our LoS calculations when pawns are standing directly at the corner of the wall.
