If you're able to join the discord I can send you a single map file that SHOULD fix the issue without having to upload a new build, if you're not able to, I would come back to that quest at the next build o/ should be up and running now. Also, the Aegis Crest is being equipped normally in my version. If you have an OLD version of the Aegis shield, it may not have the appropriate mod slot on it as it was a later addition. Due to how the game handles equipment, a new version of Aegis shield may have to be acquired. Sorry about that!
