Originally I used Plentiful Traditions. While I have since moved to Expanded Stellaris Traditions, you can find a Plnetiful Traditions Addon to go with it, giving a lot more slots for perks.

You can find the Plentiful Tradition Addition here.

Has anyone found a solution for only having 20 slots?
@Akura what traditions mod did you use to expand the UI?

Yup - I don't mind helping if people bring it up to me.

I found the culprit "RPG Traits Core [Official Version]" was replacing the "Ascension Theory" tech for some reason. So it was a mod conflict on my end and removing that mod fixed the issue. Thank you for your help.

Okay. So, I took a look at it, and I am still seeing it pop up. So, it is either that another mod is conflicting with it, OR, you've just gotten very unlucky. The best way I can suggest to check this, is to start up a non-Ironman game, use console commands to rush through technology. Get to where Ascension Theory pops up, research it. Afterwards, do "techweights soc", or instead of soc, you can use eng or phy. If you see something come up with "Societal Ascension", "Computational Ascension", or "Industrial Ascension", they should be able to come up, and it's just been a matter of poor luck. They are rare finds, even if they don't have the purple color.

I can take a look at it this weekend, if not tonight. The new DLC might have caused a problem.

I have researched every tech option that there is, even the repeatable ones many times over and the "Ascension Theory" one a while ago but still no new tech options added by this mod.

Yes, that fixed it. Thank you for the quick fix. Very impressive work.

There - try it now. You should be able to get the tradition now.

It shouldn't affect traditions at all, but I'll be taking a look here in a moment myself. As far as the techs go - you have to research the vanilla "Ascension Theory" perk as a gateway. It's a rare one, and typically seen at the end of a game.

It started when I activated this mod and stopped when I deactivated this mod. It is consistent thoughout gameplay when the mod is active.

If you would like me to work on fixing it, I may need your assistance in regards to details on when / where this happened.

This makes my "Databank Uplinks" tradition vanish and the ascention tech option does not appear at all.

thats completely understand and like you said there seems to be no problems with the miss match :)

I have seen no problems either using it while it's marked as 2.0, so currently I will not - but if I make any changes or additions to it, I likely would then. Work, among other things IRL keep me a bit busy, so I can't always stay on top of my mods, but I do what I can.

any plans to upgrade this mod so its up2date with 2.0.1? :)
(although i already tried using it, and found no problems so fare) ;)

Well, if you know of a place that could show me (or a person perhaps) how to adjust the UI, I could try to add that in. Until then though... You may have to get a tradition mod to go with it. I know of two that could potentially work. It is up to you if you want to use them or not though.

Expanded Stellaris Traditions:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=946222466
(This one will add more traditions, and should increase the UI enough that my mod will add all 24 slots.)

Plentiful Traditions:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1311725711
(Though the original is no longer updated, this one is 2.0 workable. It will increase the ascension perk slots to 42 or 43 I believe. Even without my mod, but my mod can make them more obtainable by giving the repeating techs.)

I actually tried the mod with no other mods installed.

It fills the empty space up with 20 slots only until the space is full.

Which is damn sad because I really wanted a 24 Ascension Perks only mod :'(

It should add 24. I have had no problems. I believe there are 2 ways it might not show all 24.

A: You have another mod higher up in the load order that changes ascension perk slots, or...
B: Your UI does not support more than 20 perk slots. I use some tradition mods that expand the UI a little, so it may be an issue of space. Sadly, I do not know how to make more space for the slots.

When I use this mod I see slots for only 20 Ascension Perks, not 24.
