Air RB: Bomb exploding but doing no damage?

See video, as you can see, the bomb clearly hit bullseye, and exploded, flattening the buildings (graphic effect). But the base marker shows no sign of damage! A second bomb to the same base, also no damage.

I have seen this on occasion now.
Particularly frequent if you use the Mk.13 mines as bombs (With the PBY-5 Catalinas).

You can bug report it here (just search a bit first so that you don’t report something that is already reported and known about): (Gaijin.net // Issues)

A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki)
