Hello. I have been doing the Imperial Legion quests and after doing the Damsel quest, my Morrowind guide said to kill two giant netchs near Gnaar Mok too before returning to Moonmoth Fort because thats the next objective. So I killed one of the netchs and it said something in a box like "You have killed a breeding netch" and then I killed another and it didn't say anything that I know of. So I went back to Moonmoth and turned in the Damsel quest and got the new one but I haven't been able to turn it in. I have killed several more netches but still no credit. I tried typing "ra" in console command and then killing two but that didn't work either. I have no other saves to fall back on either. Thanks for any help provided.

I think maybe I need to kill a bull aswell? Guide didn't mention it but I just read that somewhere.

Yes, a bull and a betty netch are the breeding netches.

And not just any bull and betty, but a particular two near Gnaar Mok. Sounds like you got one, now you need to find and kill the other.
