Regular Mods can't permanently delete any topic or well any post for that matter, when Mods delete anything it end up in a removed content section and still could be restored it if need be.. however I don't see the Drastic thread there... so not sure what is up.. I think EvilDragon needs to step in.
Edit: wait I see it, a certain Mod from down under, accidentally merged the Drastic thread with the "Drastic cheats are not working" thread instead of the other way around.. I'll rename it, I'm not sure if I can restore it to the original thread ID.
