I'm assuming the reference to the mod is creature_adventurecraft, which is what I named the file that adds the four new monsters.
And first thing I see is the travel advisory bug. If I recall it's somewhere in the announcements file, in the init folder. Apparently code for that announcement was removed when it got changed to display the "reason you can't currently fast travel" statement on the fast travel screen.
Other than that, I'm not sure what else might be causing problems. Though for generated creatures they shouldn't be citing essence materials because only megabeasts are supposed to have them. >.<
EDIT: Oh wait, it is also derping out over my having dummied out the humanoid joints and upper spine body tokens, due to having replaced them with joint definitions on the body tokens themselves.
EDIT 2: I am however spotting miscellaineous mistakes on my part to fix. Mantises reference the wrong name for tanned chitin, giant brown recluse spiders being set to drop venom sacs from their non-existent stingers (instead of mouth), gargoyles having the hoof material template but not the hoof tissue template...
EDIT 3: Ahah, essence error spam is because I retained my outdated method of implementing megabeast hearts that left references to the MEGAHEART material in every creature, when I could instead be citing it only in the entries for the creatures that need them. >.>
EDIT 4: Fix is up, but I still have no idea what would've caused a game crash.
I'm glad it helped, Im not sure why this caused a crash in dwarf mode though. Worked fine in adventure mode.
I do not like the fact that 7 days to die went from a fairly fun and decently unique game into pure Rust. Might still play it though, because it is a lot of fun.
7 Days To Die is the reason why I unsubbed from "Is It Worth A Buy", I bought the game expecting this crazy survival game that was "THE SURVIVAL GAME" so I bought a copy for me and my mom since I was getting burned out on Minecraft and I thought, "Hey it's like Minecraft me and her can get into it."
We never found each other and when we did we died from starvation, zombies, etc... etc... and I know "muh realisms", but I came here to play co-op so what's the fucking point of spawning your friend hundreds of meters away.
So I did it solo for a while and got bored. The game isn't that great looking, I'm not a fan of the gameplay, and it's just kinda 'meh' overall. I hope it'll improve with more updates. But I'd rather just play Rust or Project Zomboid, since they're doing the whole survival in a post-apoc environment really well... even though I've burned out myself on both games.
I thought about it, and I think I wouldn't be so turned off of 7days if they had just said "we took inspiration from other games!" instead of saying "ORIGINAL SYSTEM! OUR IDEA! DO NOT COPY! DEFINITELY NOT A COPY OF OTHER VERY POPULAR GAMES WAY OF DOING THINGS! WE BAN YOU IF YOU SAY IT IS! OUR FANS WILL CASTRATE YOU IF YOU EVEN THINK ITS LIKE THAT OTHER THING, EVEN FOR A SPLIT SECOND!"
