Going Medieval Jonathan Bug Fix: Restore Settler Names & Fix Freezing (2026)

If you’ve been deep into Going Medieval lately, you already know 2026 has been wild. The full release brought in some seriously cool systems—water mechanics, smarter diplomacy, better world interactions. But it also unleashed one of the strangest bugs I’ve ever seen in a colony sim.

I’m talking about the “Jonathan Bug.”

And yeah… it’s exactly as weird as it sounds.

So… What Actually Happened in My Game?

Picture this: I sent out a solid caravan—good gear, reliable settlers, even a couple of animals. Everything was fine. They come back, I unpause… and suddenly my entire colony is named Jonathan.

Not just one guy. Not just the caravan. Everyone. Even the animals.

At first I laughed. Then I realized the game was basically breaking in real time: UI portraits turned into blank or weird placeholder icons, the camera got stuck like it forgot how to exist, settlers stood frozen like they were part of some medieval art installation, and tasks were completely ignored.

It went from funny to “oh no, my save is dead” in about 30 seconds.

Why This Bug Feels So Creepy (and Kinda Legendary)

I’ve seen bugs. I’ve played early access games for years. But this one hits differently.

There’s something genuinely unsettling about seeing a thriving colony—people you’ve named, managed, saved from raids—suddenly reduced to identical clones called Jonathan.

From what I’ve gathered digging through community threads and developer notes, this comes down to a fallback string error. When the game fails to load character identity data properly, it replaces everything with a default internal name.

Basically, the game forgets who your settlers are and just calls them Jonathan.

It’s like a medieval version of a database amnesia glitch.

Why It Blew Up in 2026

This didn’t just randomly appear—it exploded after the big system overhaul tied to world interactions and caravans.

The game reworked how off-map areas function, introduced stronger save compression, and adjusted settler identity handling. Somewhere in that process, identity IDs started misfiring during transitions.

And that’s why most players triggered it the same way: caravan leaves, caravan returns, everything becomes Jonathan.

The Fixes That Actually Worked (From My Experience)

1. Verify Game Files (The Real Fix)

This is the only method that consistently worked long-term.

Close the game
Open Steam
Go to properties and installed files
Click “Verify integrity of game files”

After doing this, my game stopped breaking on caravan returns.

Best for: Permanent fix

Important: Reload a save before the caravan returns if possible

2. The “Press F” Trick (Weirdly Works Sometimes)

This one feels like black magic, but it worked for me once.

Select a settler
Press F to focus the camera

This forces the game to re-anchor the character position and sometimes the UI snaps back.

Best for: Quick recovery mid-bug

Success rate: Inconsistent but worth trying

3. Clearing Cache (If Things Stay Broken)

If the bug keeps happening across saves, this is your next move.

Navigate to the local game folder
Delete logs and crash files
Restart your PC

It clears out corrupted temporary data and can stabilize the game.

Best for: Persistent glitches

How I Avoid Triggering It Now

After getting burned once, I started playing more carefully around caravans.

Always make a manual save before caravan returns
Avoid overlapping events like raids and traders
Keep caravans smaller
Do not use fast-forward right before arrival

It’s not ideal, but it significantly reduces the chances of the bug appearing.

Quick Reference Table

Issue Trigger	What Happens	Best Fix
Caravan returns	All settlers renamed “Jonathan”	Verify game files
UI fails to load	Blank icons or missing portraits	Press F or reload save
Camera locks	Cannot move or zoom	F key or restart
Persistent across saves	Bug repeats every session	Clear cache and verify files
Mod conflicts	Identity system breaks	Disable outdated mods

If You Use Mods — Be Careful

This is a big one. If you’re running mods, especially anything that affects UI, settler stats, or traits, you’re much more likely to encounter this bug.

Many mods haven’t been updated for the new identity system, which creates conflicts.
