Can’t educate a child in Crusader Kings III? It’s probably not your fault. Since the 1.20 update, many players get the error “This interaction is no longer valid to send” when they try to assign a guardian. The quick fix is to save and reload your game. I searched for the solution and with the help of Reddit I found the fix and the other things that can block education.
Inside This Guide:
CK3 Can’t Educate Child After the 1.20 Update
Update 1.20 “Crozier” came out on September 30, and players started reporting this bug right after. It usually goes like this:
- You pick Educate Child and choose a valid child and guardian.
- The confirm button stops working.
- The game says “This interaction is no longer valid to send.”
It hits your own kids, your grandkids and random courtiers. It doesn’t look like a mod or religion problem. Players get it as feudal rulers and adventurers, and one Steam player says it happens with no mods and no DLC.
Hotfix 1.20.0.3 (October 1) doesn’t list a fix for it, and players were still reporting the bug on October 4. As of October 5, there’s no official fix.
How to Fix CK3 Can’t Educate Child
The best fix so far is the one players share on Reddit:
- Save your game.
- Load that save. Going to the menu and loading it back is enough for most players.
- If that doesn’t work, close CK3 and start it again.
- Assign your guardians.
Unfortunately this fix is temporary. One player got it to break after about five interactions. Another one after two. So you most probably have to do this every once in a while.
CK3 “Is a Child” Crusade Beneficiary Bug
If you are one of the unlucky ones you’ll encounter a second bug at the same time. When you pick a beneficiary for a crusade, the game says an adult is a child. And this has happened with a 25 or even a 49 year old.
It’s most likely the same bug, and save and reload fixes it too. One player noticed it started right after educating a child. A Steam player also reports “no valid character found” when looking for spouses.
Other Reasons You Can’t Educate a Child in CK3
If only one child or one guardian is blocked, or reloading doesn’t help, check these:
- The guardian is full. A guardian can normally have two wards. A new courtier may arrive still teaching kids from their old court. Update 1.20 also added the missing text for this rule, so the game should explain it better now.
- The child already has a guardian. Remove the old guardian first.
- Illness. In an April 2026 thread, a player couldn’t educate his kids. He traced it to Consumption, which both he and the children had. Check for serious illness on both characters.
- Mods. Mods that change education, like Better AI Education and Auto Guardian Appoint, can break the interaction. Test without mods. Paradox also asks you to turn mods off before reporting a post-update bug.
- A child ruler. One player says a child ruler’s regent is their educator and can’t be changed. This comes from one comment, so take it with care.
