Running the latest version of XLights. I have a model that I use sub models, this model was added for the 2021 holiday season to existing sequences. I updated many sequences with the new model using the sub models this spring. The sub models worked as expected! Recently I started to finish sequencing the rest of my sequences for 2021, I put an effect into the sub model line, test it, all is good. I put an effect into the main model, it covers over the sub model. I have check the early sequenced sequences they are fine.
