Just in case you dont check the other thread where I replied:

That's a default Unity error message that has questionable phrasing. Essentially the game will create a folder with the date/time of the crash as the name - in your case 2016-06-25_0301224. The folder should be located where chronicle.exe is located, which will be Steam\steamapps\common\Chronicle

Inside the folder will be the crash logs and some dump files. The main one is output_log.txt, which with a bit of luck should have the crash information in. Copy the contents of the output_log to somewhere like Pastebin and provide the link.

Unfortunately at the moment there's no way to submit the crash files directly.

That's the first time I've seen that error in this game! Certainly seems to be an issue regarding the graphics card / drivers, given the spam of: d3d11: attempt to lock null index buffer.

Two things you may want to try. First is see if there's any updates for your graphics drivers on Nvidia's website - I'm assuming drivers may be out of date, so updated ones could fix this issue.

Alternatively you could try running the game in DX9 mode, but this is not officially supported. To do this, right click on Chronicle in the Steam library, select Properties and then click Set Launch Options. In the box there, paste the following:

-force-d3d9

Click Ok, and the game should now run in DX9 mode. Just be aware that there may be a few black textures or small rendering issues.
