Below is the error i get from the debug log inside the game. This happens when I generate a Lombax using Prepare Carefully. If the Lombax is automatically generated by Rimworld it does not trigger this error.
The error keeps pinging for ever. :(

Pawns spawn without errors with EDB for me. It's a problem at your side.

And for you to know, EDB prepare carefully sometimes have issues with alien races. All what i can do is recommend you to reinstall all the mods or to use "character editor" mod.

Ohh yea, i'm well aware. I got 7,000 hours on the Rim. My guess as to what happened on this error was that during character generation I made some physical modifications to the Lombax pawn i generated through EDB. What ever that was, the game did not like it.

I created a new game, and twiked with it a bit but was unable to replicate the error. As of now it is working smoothly after re-started the colony.

Thanks for your quick replies.

Not sure if this is an error, but whenever I start with the lombax start that comes with this mod, I always have my starting pawns get hypothermia when naked. Their base min temp is in the 80s for me and I have to scramble to get them clothing so they don't die right away. Is this intended?

Their min temperature requirements is 30 Celsius. Yes, this is intended because lombax is extremophile, try to live at desert worlds for thousands years.

This isn't a bug with your mod, but this seems to be the best place to put the error logs. It appears to be incompatible with Children and Pregnancy (https://ludeon.com/forums/index.php?topic=51258.0) and some sort of conflict prevents the modular ears/eye/tail sprites from displaying, while also breaking the sprite scaling.

The lombaxes look like horror monsters for me, they have no face and I don't have C&P like the last poster does. Log sharing won't work rn, I'll add a log once it does
