In the pocket dimension, i had a code i'd gotten and when i tried to connect to that code, the game said: "Tesla_coil.png not found! The Game will probably crash!" or close enough. It seems like this is a pretty big error... I did re-install and load up my save. Still no joy. Perhaps the developers accidentally left it out? or didn't finish it?
Let me guess. You do not have the YHTNTEP DLC? (You Have to Name The Expansion Pack) It is the free one. Steam and most other methods to get the game ironically do not usually bundle it with the rest. Here is a link for the Steam version. If you have a different version we will have to look a bit to find it. But it will cost you nothing. http://store.steampowered.com/app/98821/
Ah. I was missing that particular DLC. Why would the vanilla game call on a DLC product like that? I know it's free, but surely other people will/have had this issue... just seems a bit strange to me, but it's not my game. At least it was an easily resolved problem.
