Here’s a step-by-step guide for installing the Medieval Kingdoms 1212 AD – Base Pack Campaign Alpha (typically for Total War: Attila):
| Issue | Fix |
|-------|-----|
| Vanilla Attila loads instead | Check load order; Base Pack must be last. |
| Crashes on campaign start | Verify game files (Steam → Attila → Properties → Local Files). |
| Missing UI / invisible units | Re-subscribe to Models pack; delete data\ folder remnants of old mods. |
| End turn freeze | Reload save; avoid alt-tabbing during AI turns. |

You cannot run this mod on Total War: ROME II or Thrones of Britannia. You need the ATTILA executable. You do not need any DLC (like The Last Roman or Age of Charlemagne), though some sub-mods may utilize their assets.
Total War: ATTILA’s default launcher is notoriously bad at loading large mods. Download Kaedrin’s Mod Manager (for ATTILA) or use the ATTILA Mod Manager from Nexus Mods. This tool allows you to set load orders properly.
