Quick triage

• 1) Update to the latest pack zip and packwiz refresh if you maintain a fork.
• 2) Remove any custom mods you added; re-test with the stock modpack.
• 3) Clear shader/resourcepack overrides to rule out bad assets.
• 4) Ensure Java 21+ and at least 6–8 GB RAM allocated.

Mod incompatibilities

If you added mods yourself and see crashes or missing textures:

• • Reproduce the issue with only your added mod + stock pack.
• • Capture latest logs/latest.log and crash-reports/* if present.
• • Note the exact mod name, version, and steps to trigger the problem.

Post these details to us via GitHub issues (button below).

When the game hard-crashes

Crash Assistant will open with instructions. Follow it to gather:

• • latest.log and any other log files.
• • The Crash Assistant summary text or screenshot.
• • Steps to reproduce.

Attach these to the GitHub issue. If Crash Assistant didn’t appear, copy the crash report from crash-reports.

Server

• • Make sure you are running only server-side mods or mods marked as both
• • Your server should at least have 6–8 GB RAM allocated.
• • If you cannot resolve the issue that way, open an issue with the crash report or log file.
