v0.3.1

Fixes:

• Craft a filtered list instead of modifying existing one prior to preStep: When preStep is used, there is a list of resources that is pre-computed to be inyected and used there. Previously we were cleaning the main list of resources instead of crafting a new one to save some resources. This caused a but as we were iterating and modifying the list at the same time. Now, the process crafts a new filtered list to avoid collisions
