Shotgun trap can't shoot through netting.

Hey, I have a netting in my base for climbing to next floor. I have placed some chests and a shotgun trap behind it so it could shoot people when climbing the netting (like a auto turret shooting from inside of chainling fences or prison walls). But unlike the auto turret-prison wall- chainlink fence tactic, my shotgun trap's bullets don't go through the netting. It is getting triggered but cant shoot people behind the netting and netting is getting damaged only. I request a fix for this. If chainlink fences and prison walls work this way, a netting made of ropes shouldn't be bulletproof too. Thanks.
