Black Blocks SpriteFont on iOS 7.1

Hello,

I am using MonoGame with iOS on a Mac using the emulators. I have no device.
I created the xnb files with the MonoGameContentProcessor on a Windows machine.
When I run the app on the iOS 7.0 emulator, everything is perfect. But when I run on any iOS 7.1 emulator, I get black blocks for some fonts (not all fonts). What could be wrong?

Thanks.

Okay. For those fonts causing problems on iOS 7.1, I resolved the issue by increasing their sizes by 1 pixel. Still don’t know why the problem exists and is on 7.1 only.

If you turn it back down again does it still happen?
Sounds like they just needed to be rebuilt

You are correct. Turned them back down and they work fine.

Thanks.
