Hello!

I upgraded my solution via nuGet, and now i'm unable to save & publish from code. I keep getting the next error:

ERROR Umbraco.Core.UmbracoApplicationBase - [Thread 379] An unhandled exception occurred

Wierd part here is, that I have one document, which i'm able to save & publish from code, but all others keep failing after the upgrade, and from what I've searched, I can't find any difference between the working document and the rest. I'm able to create NEW content, but can't update old
