Cannot complete tutorial quest "Positive Reinforcement"

[lailacampos]

All the topics regarding this issue were archived, so here you go.

After enhancing my weapon prior to accepting the quest "Positive Reinforcement", I'm left unable to complete it.

I'm a completionist freak, so abandoning a quest really bothers me. Is there anything that can be done about it?

 

*Edit: To everyone who wants to solve this, just go to the beach and kill some crabs until you get a weapon drop, then evolve your weapon. This should allow you to advance the quest.
