This bug allows you to drive and discover the big lake as a submarine. Interesting is, that if you have the Winter Barn Find activated, but missed to collect it in the Winter, this is also a way to get the barn find without being in winter.
This bug only works in all seasons except winter.
To reproduce this do as follows:
- Go to the menu under “Rivals”
- Select the big button “Choose Race discipline”
- Select Drag Race as your discipline
- Select the ice surface Drag Race
- Drive the race, and end the race via the menu, while on the ice surface
I also made an imgur album for those who couldn’t understand the reproduction: Drive IN the Derwent Water - Album on Imgur
After completion, the game tries to reset you, but it fails. You will get a short black screen. After that you can explore the underseas.
