Friendly Ship Shopkeepers Crash my game

Everytime I go onto a friendly ship to buy from the shopkeeper with the little mechanical backpack my game freezes and crashes. is there any way for me to trade with him/her without my game crashing.

 

Me and my bf am getting this too. Did you ever find out a way to overcome this? If you're using any mods, what kind of mods?
I have the error report somewhere and normally I am able to pinpoint what's wrong but it's just saying that the conversation (The words they say or the menu that comes up) aren't 'legal' or something by the game's standards. And as far as I can tell, this bug only affects the friendly ships containing multiple races wearing space suits and backpacks (The ones you can find in the hidden chests in the Erchius Mining Outpost).

 

Here's a Pastebin of it.

What catches my eye though is:

Or more specifically, the part about the shopkeep's window. I went and tested this without any mods and found the same problem with the NPC's. It only affects the merchant onboard a friendly ship where the NPC's all wear spacesuits and backpacks (The one from the erchius mission). Both me and my bf encounter this issue on our LAN server, and in singleplayer. Server doesn't crash when this happens, just the client, and it's not a total crash either. Just a kick to the main menu. So there's nothing wrong with the NPC in particular, just the interface that comes up, or something in it.

 

Maybe I should have emboldened it, but I DID test it without mods right afterwards, by making a backup of the character and sending him to a vanilla singleplayer to go to this guy; he still crashes my game with the same error. I originally did this because I thought it might be the mod I have that makes NPC merchants reset their inventory an x amount of days, however the only NPC that seems to crash clients is the one mentioned and even in vanilla the problem occurs. I don't know why this isn't all over the place, but if this still happens to me in vanilla, then I'm inclined to believe it's a product of vanilla.

I will try reproduce this in a fresh vanilla run, I have to start a new character and find that ship again elsewhere, but the ship only seems to be one of the rare ships that I don't see often (I've seen maybe 3 types of friendly ships and mostly hostile ones, and the other two friendly ships that I see are way more common than this one.

Speaking of friendly ship bugs, one of the other friendly ships doesn't have atmosphere inside of the ship itself. I could be landed and have normal gravity and where the NPC's walk about but there's no oxygen to breath. I don't remember which one, but it wasn't the same one as the bugged merchant.
