@mayonnaise happy to help. Unfortunately, I still wasn't able to replicate the issue with any of the listed relationship types (using various murder methods on a family of one gma, one gaunt, two single mothers, and a pair of children from each mother), using
1) just my mods
2) the error-implicated roster of mods applied to the same save file
3) a brand new save file using the error roster from the very start
4) or a brand new save file using the error roster from the very start, with Big and Small - Framework above Odyssey

Therefore, the actual culprit(s) are hidden elsewhere in your modlist, and whatever is causing the error occurs so far up the chain of logic that's supposed to occur on kill it can't be directly seen in the error log. Sorry.

thank you! i appreciate you taking your time to help me out here :>

@mayonnaise testing my way through it now. I can tell you that with my mods running, I can kill a grandchild perfectly fine, but let me try with other 2nd-gen family relationships and with the fuller mod list.

@Hauts after some testing, it seems that only pawns with second generation family relationships (grandaunt, granduncle, grandparents, nephew/nieces, etc) make a pawn unable to die. at least, that's what i've concluded. if you could test it again, i'd be very appreciative :>

oh. nevermind. for some reason exiting in and out of the menu WITHOUT saving changes shows the effects. i... thiiiiink? will report back. :>

@Hauts ah! good suggestion, but for some reason the "auto-sort mods" button in the mods menu doesn't seem to actually sort any mods; the list remains exactly the same. don't think it should be doing that either!

@mayonnaise thanks for the report, but I think you've got the wrong culprit. I loaded up all the mods directly implicated in the error message or required for those mods (Big and Small - Framework, HugsLib, VEF, VPE, VAE Accessories, VFE Empire, VFE Deserters, Allow Tool, Gore Upon Dismemberment, my framework, HAT, Allow Consensual Incest, VSIE, Ragdoll Physics, VAE Insanity, Alpha Genes, Animals Logic) in the same order you have them, and was unable to replicate the issue.

For your woes, however, I suggest you press "Auto-sort mods". Big and Small - Framework should be below Odyssey, and the fact that it's above Odyssey in your modlist suggests to me that other mods that should be below others aren't in the right positions either, which is liable to cause all sorts of errors when you have tons of mods running.

i'm having some weird error where pawns who have any family relations are literally unable to die; signs are pointing towards your mods. i'm unfortunately not able to test this on my side so i figured i'd just make you aware in case anything comes of it.

note how you have a Harmony patch on RecordsUtility.Notify_PawnKilled, and the error is happening around RimWorld.Pawn_RelationsTracker.Notify_PawnKilled

hope this is useful and not a red herring

@FrozenSnowFox thanks, should be fixed now.

Found some more errors when your Framework and Trait mod are active with Tweaks Galore.

Oh damn, I was just verifying the Vanilla Psycasts Expanded incompatibility when I saw you'd already addressed it. Good stuff Hauts, much appreciated.

Thanks for the quick work on both mods @Hauts! I'm error free (from your mods at least) now!

@azrazalea, @FrozenSnowFox fixed.

This would be what people reported below. In 1.6 the Vanilla Expanded Framework changed a bunch of classes. So some errors are coming from the Psycasts patches.

The psycasts Defs were
VFECore.Abilities.AbilityDef
They're now
VEF.Abilities.AbilityDef

@Hauts its fixed! thanks so much :D

@fayestar just put up an update to address that. Tell me if the issue still pops up.

opened up an issue on github with missing "extract hemogen pack" operation bill!

Opened an issue regarding disappearing info cards through GitHub.

@Hauts It works! Thank you ^^

@ ♥ Aevery Windchild ♥ it should be fixed now, let me know if that's not the case. (Also, thanks for being the first person to actually submit an error log and modlist)

Seems to have an issue with VPE - Puppeteer, the Puppet ability can't finish casting and returns an error.
Opened an issue with the details on the GitHub page.
