Hi @yimika ,
Do you have a sample file that recreates this issue?
We recently made a change in the URBANopt workflow so that more data from the dragonfly models can be translated to the OSMs used in the URBANopt simulation. The URBANopt team also made some big changes with version 1.2 so that Ruby gems don’t have to be re-downloaded each time that you create a new project folder. It’s possible that there may be a bug that resulted from one of these changes.
