Hi, I found some pretty bad bugs when worker animations are on. First, in this picture, the 3 models that surround you and aren't in view at start are invisible as is the whole city model (the city loads when looking at the very center of it). Second, on the 1 model in front that does load , if you turn away from it so that its not in view, the animations completely freeze.
EDIT: If lights are on, when looking away from the model that also freezes the animations, the model bakes the lights and stops updating.
EDIT: The model looks weird with backface cull on.

2-48-5 animations do not freeze and models are visible.
