Description
Apparently grass algorithms are unable to read as input temporary layers from previous algorithms. I tried on two PCs, both using the OSGeo4W and the standalone installer, always performing clean install after full removal. I tried with many different sequences of algorithms and various valid datasets. Below a sample of what I constantly get in the modeler log:
