Lately, whenever I complete a quest that would net me a possible crew member the game just freezes for a minute or so and then the NPC will just simply cease to be (they vanish). Thus far, I've only noticed this with modded races like the Avali or the races from the Elithian Races mod. Here's my log from my most recent session in which this occured. Last time I looked over my log when this occured I noticed nothing wrong other than an unrelated glitch keeping me from getting an achievement.

Should add that my game briefly freezing up was a thing that happened in the past but it never made the NPCs vanish like this.

Whenever I revert my crew members to there orignal outfits they lose there hats and don't get them back.

@CharizardsFire, If im right you are talking about the elithan races mod npcs. This is fixed in the current version of this mod on the starbound forums and will be on here soon enough.

What is basically happening is that the hat isn't actually part of the uniform, but is an item that the crewmember spawns with by default so the uniform assignment won't assign a new one. The saving of original clothing should have caught the hat and saved it as the original clothing but for spawned in crew members the saving was not as robust as it should have been becasue we did not expect crewmwnbers to be spawned in like they were and was more there as a catch to prevent any crashes or broken scripts due to unexpected scenerios, like this one.

I noticed that with this mod installed the job offers from job offers are no longer consumed on use as intended.

I'm not sure why, but Tailors and tailor recruits no longer function as intended with this mod active. They'll simply state a default "good outfit choice, captain" with no UI or anything showing. Trying to investigate my save file has revealed nothing and I am now permanently stuck with the inability to customize my crew.

I saw in the mod comments that I'm not the only experiencing this, but I have some crew members that have helmets from favor quests and the tailor will overwrite everything but the helmet when selecting the 'Outfit' option. 'Uniform' will remove the helmet, and 'Original' puts it back on (since they had it when they were recruited); using 'Uniform' to remove the helmet and then 'Outfit' to replace it seems to work, but is a little obtuse.

Every time I try to change the crew's uniform, only their hats change.
