With regard to this bug (Shot through the wall) and it is a bug, not a feature, could you properly inform the community about it in some sort of changelog or add it to the description of shot modules?
Sorry guys, but it is poorly implemented and I don’t have a problem if you want to add it to the known bugs, but it goes against the whole logic of the module. So at least acknowledge it and change the rules/descriptions accordingly or fix it. Hiding like that is a cowardly thing and till now I had a quite high opinion about you guys.
About the implementation, right now, I guess, it is done that on the place of collision there is generated explosion and if a player is in the explosion, there is a hit, but you should check if a ray from the middle of the explosion to the player is interrupted. Otherwise, it goes against the logic of the module whatever Svo as a shot player says.
