I play using Open Starbound and a large modpack that I put together for myself, and aside from one or two other issues that can be bypassed more easily, this one issue haunts me and I have no clue why. The Starbound.log file has been zero help in telling me what is wrong because the log simply doesn't write anything when I talk to him.
I have gone through and tried disabling mods one by one until something happened, but I'm not even sure if launching the game without the culprit mod would magically update him to start giving his quests - because not one of the mods I disabled made him pop up with a quest.
I will list off the mods that I have that directly affect Baron in some way, and largescale mods that might change him in some way that isn't documented due to being a minor thing.
Affects Baron Specifically
The Ol' Schooler (Short dungeon quest for a weapon)
Halloween Special: Aspect of War (Weapon quest)
Project Redemption (Weapon quest)
Anom's Outpost
Larger Content Mods
Elithian Alliance (Github Version)
Arcana
Arcana: Voyage (formerly MWH's Arcana Addon)
Betabound
The Starforge
Shellguard
Voided
Maple32
My Eternia 2.3
Races
Lastree
Indix
Saturnians
Ashspeakers House of Peace
The Kyterrans
Draconis
Avali
Vash'Knaaren
I can post my full modlist if needed. I don't expect there to be an easy solution, I'm more so just throwing this out there in case anyone else has had this exact issue with a similar assortment of mods in hopes that I don't have to rebuild a 300+ modpack over a single annoyance.
Pre-emptively, Thanks for your time anyone who ends up helping.
