In TeamCity plugin step "Redgate SQL Change Automation Build" build.version is being normalized to SemVer (for example 2.1 -> 2.1.0 or 2.1.0.0 -> 2.1.0).
Because we use these nuget packages internally only we don't need to follow SemVer. It seems that Nuget team doesn't want to remove that normalization (https://github.com/NuGet/Home/issues/3050) so solution would be to create and use custom Nuget build. Thats how Octopu Deploy solved this issue: https://github.com/OctopusDeploy/Issues/issues/2898
