I would love to try out the Engineering Tech Tree but when I install it (even with no other mods but its dependencies) it looks all tangled like this and is nigh impossible to navigate. Other screenshots I've seen don't look like this so I assume this is not right.
I've only seen one other post that looks related: https://www.reddit.com/r/KerbalSpaceProgram/comments/6brso7/tech_tree_mod_help/
but according to the thread it was a result of installing multiple tech trees. I have no other mods installed except ETTs dependencies
