I think this might have changed into a bug from a feature request. I'm no longer able to build my project - each time I try to build, I get this message:
Error 21 Files that you had modified, have pending server changes. Please pull first! C:\Program Files (x86)\MSBuild\12.0\bin\Build.targets
I try pulling down, and it says everything is up to date, but I am still unable to build. I realized that I made an update to a static resource outside of TWS, and I think the build process is seeing that it is an old version and stopping me from building, but since I can't pull down the updated Static Resource, I think I'm stuck.
