Terraria 105 with source

Downloaded and looked through. Seems very intriguing however to anyone who decides to play with this EXE there is a glitch or issue with it that causes most mobs not to spawn at all. In fact the only mob I have seen spawn is the bone serpent and even that doesn't spawn often.

So yeah just be aware of that.

I get that in my mod aswell, something about decompiling the game, then recompiling it makes monsters dislike spawning in SP. But most mods, (Including mine, and many others) are more effective in MP, where monsters do infact spawn, because I presume the server handles that and sends the information to the clients.
