I'm working on an openstudio model which is based on a DOE prototype building created by openstudio measures. I made some changes and the simulation went well without any error. After a while, I tried to run the simulation again without any change in the model and the simulation failed in initialization workflow. Here is what I found in run.log file:

[15:40:45.472844 ERROR] Found error in state 'initialization' with message ["Cannot find measure OpenStudioResults::/ruby/2.2.0/gems/openstudio-workflow-1.3.4/lib/openstudio/workflow/util/measure.rb:150:in `block in validate_measures'

I'm using version 2.9 of OpenStudio.
