Crash Utilities FAQ
19 questions players actually ask, answered.
How do I open the Crash Utilities GUI?
Press CTRL + U on your keyboard to open the Crash Utilities interface. This is a client-side feature, so you can use it in single-player or on servers where the mod is installed.
Can I see what's causing server lag?
Yes—use the chunk map view to see loaded chunks and their entity/TileEntity counts, or use the entity buildup detection to find areas with excessive mobs or block entities. The RAM usage monitor also helps you track memory consumption over time.
How do I find and remove problem TileEntities?
Use the TileEntity locator command to search for specific block entities in the world, then remove or manage them directly through the mod's interface. This is useful for tracking down lag-causing machines or broken mod blocks.
Can I access another player's inventory?
Yes, the mod includes a command to open and read player inventories for moderation and troubleshooting purposes. It also supports Curio items, so you can see equipment stored in Curio slots.
How do I get my crash reports if the server won't start?
Use the crash report retrieval command to pull log files and crash reports directly through the mod without needing file system access. This makes it easier to diagnose what went wrong.
What's the item cleanup command for?
If too many items are scattered on the ground (causing lag), you can set a threshold and the mod will automatically clear excess items. This is useful after explosions or when players farm and drop stacks of materials.
Can I teleport players across dimensions?
Yes, the mod includes a cross-dimensional teleport command that lets you send players to different worlds or dimensions, as well as a command to send players back to spawn.
Does this mod work on servers?
Yes—most features are server-side commands that admins can use, while the GUI and chunk map are client-side tools. Both work together to help diagnose and fix server problems.
Will this mod slow down my game?
The mod is designed to help *reduce* lag by identifying problem areas, but the monitoring features themselves have minimal overhead. Use the RAM tracker to verify performance impact on your setup.
Can I remove items from a player's inventory remotely?
Yes, the mod lets you read and remove items from player inventories through commands, which is useful for confiscating contraband or fixing inventory corruption issues.
