RTS Building 1.1.5-patch4
For Minecraft 1.21.1 / NeoForge and Minecraft 1.20.1 / Forge.
This patch focuses on safe recovery of RTS-placed blocks, survival unlocks, clearer interaction feedback, safer mining-drop handling, and Sophisticated Backpacks compatibility.
Player-visible changes
- Fixed tracked RTS-placed blocks being lost when “Recover RTS-placed blocks” was enabled but the player lacked the normal mining level or tool.
- Blocks that were placed through RTS and are still tracked now bypass mining-level, tool, and Silk Touch requirements during RTS recovery: if RTS can place it, RTS can recover it.
- Claims, cancelled break events, and other server protection rules are still respected.
- Fixed several features being incorrectly locked while Survival Balance was enabled.
- Area mining no longer incorrectly depends on the chain-mining plugin.
- Quick Build shapes now follow their own plugin unlocks, and rejected placement attempts provide clear feedback.
- When the RTS camera is locked, the message now explicitly tells players to install the “RTS Camera” plugin or turn off Survival Balance in the mod config.
- Fixed the normal interaction target outline disappearing in the lower half of the screen when using a fixed RTS UI scale.
- Fixed Quick Build solid/hollow buttons appearing to change while generation still used the previous mode.
- Fixed large groups of identical drops being merged into an illegal oversized ItemStack and potentially crashing the game (#123).
- Improved Sophisticated Backpacks compatibility.
- The same UUID-backed backpack keeps one RTS storage link whether it is placed in the world or worn by the player.
- Right-clicking a Sophisticated Backpack from the inventory in RTS mode now only attempts placement. If placement fails, it no longer falls back to opening the backpack UI and getting stuck.
- Newly generated client configs now disable translucent placement block ghosts by default. Existing player choices are preserved; wireframe previews and placement/destruction animations are unchanged.
Technical and compatibility changes
- Tracked-block recovery now passes through server protection events, then performs a no-drop break and returns the exact recorded block item, preventing tool checks from losing items or creating duplicate drops.
- On NeoForge 1.21.1, the mining-drop buffer now merges and splits items using each item’s legal stack size and bases fallback timing on real storage progress, reducing stalls and invalid stacks during large mining jobs.
- Plugin state is resynchronized after Survival Balance configuration changes so clients do not keep stale unlock results.
- Sophisticated Backpack links now resolve real stacks from accessory, Curios, and Accessories slots before falling back to the UUID-backed virtual handler. Forge 1.20.1 also supports the older capability API.
- Regression and contract coverage was added on both maintenance lines. The NeoForge 1.21.1 suite passed in full; the Forge 1.20.1 regular suite passed, with two previously tracked performance-debt checks remaining for later optimization.
