Maybe my game is borked, its telling me to got to town and find Neon to show her the mansion but... I am not finding her anywhere.
I had the same problem for a second, but was able to continue after completing the Sectoral Movement quest. The one were you recharge the core. Neon just appeared in the main street after that.
I have that quest, but it says I have to complete Silky Powder, which I cannot seem to trigger.
This should be the way to initiate the quest, if that still dose not work maybe try Mikosh's page on the wiki and look through it?
