Resource identifier '' has already been used in this assembly

Hi, I've been using WSP builder for quite some time now and really appreciates the functionality it delivers but recently I am getting the following error message when I'm creating items based on 'wsp workflow' template. To be more precise the following error message occurs when I'm adding a rule to an if/else component causing the .rules file to be created.

"Resource identifier '' has already been used in this assembly"

It refers to the file CSC (compilator I presume?) and when I double-click the error it says "item has been removed or deleted".

If I remove the .rules file from the workflow the build succeds.

Very strange behaviour. Hope someone can help me

Don't remove the rules files -- you need it for the rules -- remove the layouts file.
