First of all
No, we don't replace lost or deleted items or dinos. Even if it is not the fault of the affected player e.g. server crash or restart (due to mod update) during a boss fight.
The only exception is made when the loss was caused explicitly by an admin e.g. accidently or unlawfully deletion of a base.
And otherwise, how did you manage to get killed by 2 alpha raptors with a tek rex 399? those should be down in some bites.
