LootRun 1.0.5 Changelog

This update focuses on stability in large modpacks, trade-terminal quality of life, and safer price scanning.

Main Fixes

• Fixed enchanted books showing Cannot buy: No price source in the trade terminal.
• Fixed raid return/extraction teleport clearing the player's experience level and progress.
• Added exact full-stack selling support in the trade terminal so stacks with non-power-of-two counts no longer leave awkward leftovers.
• Fixed multi-select selling from the trade terminal triggering server anti-spam kicks.
• Added a dedicated batch sell packet for selected stash items. The client now sends one packet instead of many /lootrun trade sell_stash commands.
• Batch selling now validates all selected stash entries on the server, processes them together, saves once, and syncs player data once.
• Added jeiPriceScanner config for the JEI price scanner. It is enabled by default and hot-reloadable.
• Improved Create 6.x compatibility by guarding Create recipe reflection behind optional runtime checks.
• Reduced the chance of large modpacks freezing or exiting during startup because of broken third-party JEI recipe categories.
• Deferred expensive generated-price refresh behavior while editing trade prices so editing does not repeatedly rebuild prices mid-input.
• Kept the manual lootrun trade sell_stash command available for admin/debug use, but the trade screen no longer uses command spam for normal selling.

New Config

Configuration file:

config/lootrun-common.toml

Section:

[compatibility]

New option:

jeiPriceScanner = true

What it does:

• true: creative operators and singleplayer owners may scan JEI recipe layouts to provide extra generated price seeds.
• false: LootRun will not run the JEI layout scanner. This can help very large modpacks that have broken JEI categories or severe startup memory pressure.
• The option is hot-reloadable. Save the config while the game/server is running and LootRun will resync trade configuration to online players.

Why These Issues Happened

• The old multi-sell flow sent one client command per selected stash row. Selling many selected items could send many commands in one moment, which some servers treated as command/chat spam.
• Enchanted books use runtime enchantment data instead of a simple registry-item price. Some buy checks did not route through the runtime price path correctly, so the trade terminal could report no price source.
• Minecraft/Forge teleport paths can reset or desync experience data during dimension changes. LootRun now snapshots and restores player experience around internal hideout teleports.
• JEI layout scanning is useful for unusual recipe displays, but some modpacks contain JEI categories that throw errors while building recipe layouts. LootRun already catches those errors, but the scan can still be expensive in large packs, so it now has a config switch.
• Create recipe APIs can change between Create versions. LootRun now treats Create special recipe reads as optional reflective compatibility instead of assuming a fixed API shape.

Upgrade Notes

• Replace lootrun-1.0.4.jar with lootrun-1.0.5.jar.
• Clients and servers must both update to 1.0.5 because the network protocol changed for the new batch sell packet.
• If a server or LAN pack still feels slow while opening a world, try setting jeiPriceScanner = false in config/lootrun-common.toml.
• If JEI price scanning is disabled, normal server-side recipe pricing still works. The disabled part is only the client-side JEI layout scan for extra unusual recipe data.
• Existing trade configs and player data are kept.

Testing Checklist

• Buy an enchanted book from the trade terminal and confirm it no longer says No price source.
• Extract or return to the hideout with experience levels and confirm the experience is preserved.
• Select many stash items in the trade terminal and sell them at once, then confirm the server does not kick the player for spam.
• Sell a stack with a non-power-of-two count and confirm the full-stack sell action can sell the whole stack.
• In a large modpack with JEI installed, start a world with jeiPriceScanner = true, then toggle it to false and confirm the config hot reloads without restart.
• Test with Create 6.x installed and confirm LootRun no longer crashes from Create recipe API differences.
