Will there be an update to 4.0?

This mod has been updated for version 3.12.3.

I see, i'll play without it then.
Thanks for responding so quickly!

Yes there is a change which has an effect on veteran classes. If there was a code/format change in that particular file, then things may be messed up because of it. Based on the recent frequency of patches/changes at the end of last year, I currently plan to wait and update all of my mods once it seems clear that the official version is relatively stable.

Did you happen to change the veteran classes for leaders by any chance?

I started my first 3.11 test run recently and noticed that almost all leaders start out with a veteran class, but instead of it being indicated seperate from the other traits below the official/commander/scientist class icon they are now listed like regular leader traits

They also don't get any regular starting perks, or only 1 if they get a negative one aswell.

Am not sure if this mod is the cause of it, but it was the only one i found that said something about leader traits that wasn't updated to 3.11 yet, so i thought i'd ask just in case.

This mod has now been updated and confirmed for version 3.10.4.

Not a problem, I'm happy to see people are enjoying them!

Fair, thanks for sharing all these mods with us btw.

Yes, there were many changes in 3.10 that would blow up with this mod. I currently plan on waiting until they put out a couple of patches and the pace slows down a bit before I consider updating again to the current version.

Not sure if you are aware but it seems like the current version of this mod is no longer compatible with the new 3.10 update.
Or atleast i noticed that species traits that affect leader lifespan no longer list them in the species creation screen.
