It was brought to my attention by somebody on Steam that my grenades were stepping on other mods grenades... (i.e. you couldn't use other addon grenades, etc.) so tomorrow I'll upload a fix (sometimes stuff like this takes a few hours to knock out) I'll upload a fix for that as while it's not killing people, it's something that needs to be addressed. So you'll get some things (like that RPG) quicker. I had hoped to develop more of the rounds, but instead you'll get the normal HE round for now, as there are a few more I can mess with, as well as other things.
