| Error | Likely Cause | Solution | |-------|--------------|----------| | java.lang.NoClassDefFoundError | Missing dependency | Install required libraries (check mod description). | | Mod 'questbook' requires version 1.12-14.23.5.2768 of Forge | Wrong Forge version | Update Forge to the recommended build for 1.12.2. | | Black screen at launch | Conflict with another mod | Remove half your mods, test, repeat (binary search). | | Quest book GUI doesn’t open | Keybind conflict | Go to Controls → QuestBook → set a new key (default: B or H). | | exp-net2 specific crashes | Network handler mismatch | Likely only works on a specific server; use in singleplayer may fail. |
