Game crashes at certain resolutions

[LeadheadOnline]

So I just heard back from a playtester, and his game loads the default main menu, (not my custom one) and then crashes as soon as he hits new game. I couldn't replicate the issue, but as soon as I switched to his screen resolution (1366 x 768) I got the exact same bug. I'm on a normal 1920 x 1080 screen. Anything I can do to make that compatible?

EDIT
Whatever this is, it would also seem to be the reason that "TEST" doesn't work in the editor unless I have "Play in fullscreen" checked.

Check the resolutions tab in the editor. Do you have several resolutions? If you have added other resolutions than the default you have to add all the assets to them too and maybe they are not updated.

So I noticed that my 0.5 assets folder was missing some of my atlases. I deleted the 0.5 folder, and added the 0.5 resolution, and it seems to have failed half way through generating the resolution. The editor closes, and the test still won't run in windowed mode
