Vaults taking no damage from Trebs and minimal damage from Bombs

Vaults are taking minimal damage from Bombs and no damage from trebs (we tested demon fire and boulders) or Orbs on official pvp servers. Bombs are only hitting vaults for a few hundred damage per bomb so the bomb investment seems way too high considering the cheap cost of a vault. I have not seen this flagged as a bug yet but hopefully you guys are aware and working on a patch before launch. If it remains unfixed the vault spam will be cancer.

Thanks for all the hard work!
