As the title states, currently I, as a client in Multiplayer take no damage from nobelisks thrown by the host or myself as client, when blown up in the vicinity nor stuck on my body directly. trees in the area I stand will get destroyed.
When the roles were reversed and I was the host, the other player who hosted the previous session DID, however, take damage when I did the same to him.
This implies that it's related to a mediocre/ bad connection from the host, as my connection as a host is very good.
I just finished testing other weapons.
Results:
Nobelisk? zero damage.
Xeno-zapper? zero damage.
Xeno-blade? zero damage.
