< white balloon 205> what s the syntax for the StackReference stack name when using S3 From this ticket it looks like it should be `projectname stackname` but it only works for me if it s just `stackname`

Yes re reading these issues I believe you are right that StackReference across stacks in the S3 backend will not work currently until <https github com pulumi pulumi issues 2522> is addressed
