I used the Cryo Bow from Realm 667, yes. In the credits, I had a link to the mod.
But I was reminded that I'm supposed to also credit the creators of the original weapon. Guess what I forgot to do?
Woops.
So, while I don't want to reupload the entire mod when all I changed is the .txt file, I don't want to look like someone who claims everything he did was his own work. So until I release v0.3, here are the names of the original Cryo Bow's creators:
ZZrionTheInsect; Bloax, Xaser, and Ethril. These names WILL be added to the .txt file upon the next version of the mod's release.
