Game Breaking Error

Game Dev Tycoon bug

This is the Error I get when ever I start up the game.

TypeError: Cannot read property ‘id’ of null

Do you use any mods?

#3

no

#4

So, you have just started up the game and it gave you this error?
I am afraid you need to reinstall it.

#5

I have done that about a hundred times.

#6

What version do you use?
The Steam one, Windows Store, desktop?

#7

Hey, have you ever used any mods at all in the past on that save game?
I would suggest starting a new game. To do this as soon as the game hits the ‘click to continue’ screen press the ‘escape’ key and select ‘new’ from the menu. The error message may remain but once closed via the ‘x’ it should not recur.

#8

I have used mods in the past.

#9

Steam

#10

@Charlie I just did as you said and it did the same thing.

#11

I am afraid you will need to COMPLETELY reinstall Game Dev Tycoon.

@Sabre_Ben35

I’d personally recommend doing the following things (in order):

  1. Delete all of your saves.
  2. All of them.
  3. Uninstall GDT
  4. Go into your steamapps/common folder and delete the Game Dev Tycoon folder. (This is a remainder of uninstalling the game via steam)
  5. Reinstall the game
  6. Hope that it works

You will also need to disable the Steam Cloud service to stop your saves from downloading again:

  1. In your Steam Library, right-click on Game Dev Tycoon and select “Properties.”
  2. Click the “Updates” tab.
  3. Uncheck “Enable Steam Cloud synchronization for Game Dev Tycoon.”
  4. Click "Close."And I would add that after completing a clean install it is

Be sure to hit escape and choose new to start a new game.
