I've got an odd situation happenning in TeamCity.
I have a build configuration that performs two steps - An MSBuild Runner and then a NuPack step.
I've watched the project work directory fill up during the checkout and I've checked that all the files for the NuGet package step are there and they are.
As soon as the first Build step completes it deletes all the files the NuPack step needs in order to work. The Build step starts a very simple MSBuild .proj file that just starts the build process, nothing fancy.
How can I tell the build step to leave the files behind?
