title: RavenDB: Object Field Value Being Rounded At Random
body: <p>First up, I want to apologise for the somewhat ambiguous question title, but I have literally no idea how else to describe this bizarre issue. Effectively, I have a document store inside of RavenDB, and despite trying to change it, there seems to be weird constraints that cause it to randomly round it to different values.</p>
  
  <p>This is best shown through this gif I made of it:

  <p>Within the C# class that this is being created from, it's being stored as a ulong, and everything is right within the code <em>until</em> it's being loaded. At which point I have an ID mismatch. As you can see, the document name is the ID I am trying to paste in, they are meant to match; but I am being hit with this very weird glitch instead.</p>
  
  <p>Does anyone have an idea?</p>
