Mojira

Mojira is a both client and server-side mod that fixes a handful of bugs reported to Minecraft's official bug reporting website, yet neglected for a long time. Now enjoy a more complete, bug-free Minecraft!

All bug fixes are toggleable in the config; feel free to disable those you don't want, as some bug fixes change the base game's functionality (e.g., minecart physics, rail duplication).

Bugs Fixed

• MC-14 (Minecarts that occupy the same space maintain their momentum)
• MC-63 (Player data and region files not written/saved to disk simultaneously, causing item loss/duplication)
• MC-201 (Field of Vision does not turn at all with a turning minecart)
• MC-577 (Mouse buttons block all inventory controls that are not default)
• MC-711 (Tile ticks of connected redstone components might be executed in the wrong order when unloading/reloading chunks)
• MC-779 (Some entities are displayed outside of their spawner)
• MC-195599 (Lightning spawners render full lightning bolt)
• MC-868 (Detector Rail switches junction before Minecart passes detector (happens only with minecarts of certain speed))
• MC-957 (Powered rails do not update when additional power sources are added or removed)
• MC-1691 (Sprinting / falling on thin blocks uses the block below for the particles)
• MC-2023 (Minecart rails break when moved with a block under certain conditions)
• MC-75716 (Pistons can create ghost blocks of rails)
