Build Tree Traversal - Trying to get files for a particular build

[Hupperware]

var builds = theTeamCityClient.Builds.ByBuildLocator(BuildLocator.WithNumber(versionNumber));

looping through each build
eachBuild.Changes is null, even though there are changes (verified by a direct API call)

When you pull changes by themselves:
var changes = theTeamCityClient.Changes.ByBuildId(IntUtil.ValueOrDefault(eachBuild.Id))
looping through changes
eachChange.Files is null, even though there are files (verified by a direct API call)

Seems that the parent object is not hydrating the children correctly.
