RTS Building 1.1.6-1.12.2-port for Forge 1.12.2

For Minecraft 1.12.2 / Forge 14.23.5.2847. The shipped mod bytecode is compatible with Java 8.

This is the first public 1.12.2 beta of RTS Building. It broadly backports the current mainline gameplay baseline and adds dedicated compatibility work for legacy Forge, rendering, input, and large modpacks. It has been exercised in both a clean development client and Multiblock Madness.

Player-visible changes

• Brings the RTS camera, remote interaction, range build/destroy, vein mining, blueprints, workflows, storage, and crafting terminals to 1.12.2.
• Fixes legacy black screens, greyed UI regions, empty secondary windows, broken right-drag camera movement, world flicker, and incomplete wireframes.
• Improves remote menus with chunk leases, menu-validity compatibility, failure diagnostics, and returning to the RTS view after closing a container.
• Protects far-distance mining drops by switching to the storage path with a player notice when normal item entities could be lost to legacy chunk unloading.
• Repairs container-overlay search, paging, slot counts, item transfer, and text/pointer input; adds JEI transfer support for the crafting terminal and common machine containers.
• Fixes Extract Only endpoints accepting inserted items and improves preservation of real stacks, NBT, durability, and capability-backed data.
• Adds request IDs and client/server diagnostics for remote menus, interactions, mining, and transfers in logs/latest.log.

Installation and compatibility

• Required dependency: MixinBooter 11.x. Modrinth launchers will treat it as a required dependency.
• This build targets classic Forge 1.12.2. Large packs contain many old coremods, custom containers, and JEI/HEI combinations, so not every third-party GUI can be guaranteed yet.
• This is a beta. Back up existing worlds before first use. Include logs/latest.log when reporting remote-menu, interaction, or drop issues.

Verification

• All 798 main tests passed.
• 153 UI Core tests passed, together with UI Kit, four-language resource, Java 8 bytecode, and production Mixin mapping gates.
• Portable GameTest: 5 passed, 0 failed; 33 real-world scenarios remain delegated to client and modpack probes.
