# Known Issues

This page is a work in progress to document more prominent known issues in Railroader.

### RR-133: Crash During Gameplay

A small percentage of players have encountered issues with Railroader crashing during a game session. The timing of this issue varies; for most it occurs after a few hours of gameplay.

You can recognize this crash by checking the `player.log`. Near the bottom you will see lines similar the following:

```
D3D11: Failed to create RenderTexture (1928 x 1080 fmt 9 aa 4), error 0x8007000e
D3D11: Failed to create RenderTexture (1928 x 1080 fmt 9 aa 1), error 0x8007000e
D3D11: Failed to create RenderTexture (1928 x 1080 fmt 19 aa 4), error 0x8007000e
```

We aren't certain what causes this crash and its rareness on most hardware has made the source difficult to track down. It appears to be some combination of Unity and/or graphics driver interaction.

If you have difficulty running Railroader again after the crash, some players have had success with a combination of the following:

* Reboot your computer.
* Restart the Graphics Driver using **Win + Ctrl + Shift + B.**
* In some cases players have reported needing to reinstall their graphics driver.

We will update this section as we learn more about this issue.

### RR-176: Crash When Quitting

Railroader may crash if you Alt-F4 the game while it is running.
