Hi @mostapha and @AlexFalcon, I came across the same issue as sentinel causing honeybee freezes. I contacted our IT to dative folders for ladybug tools (C:\Users\username\ladybug_tools) and userobject folder for honeybee component (C:\Users\username\AppData\Roaming\Grasshopper\UserObjects) but it doesn’t solve the problem. Do you mind advising if there are other locations where we should dative sentinel for? Thanks!
