So, have you modified anything lately? Installed a mod?

Upgrade to v1.1.13.

That'll probably cure it, along with a few other things.

So, you PM'd me to bump this, complete with a link, except that it doesn't help me. You need to answer the question I asked rather than trying to answer a question I didn't ask.
