SimpleClumps

SimpleClumps – Changelog

Fixed

• XP orbs respawned forever: when nearby XP didn't fit in a single orb, the orbs were removed and spawned again every tick, causing lag and flickering.
• Lost XP: XP was lost when merging orbs that vanilla had already stacked together.
• Items reset on every merge: every stack nearby was deleted and spawned again, which:
  • reset despawn timers and pickup delays
  • lost which player an item belonged to
  • turned items that can never be picked up (e.g. /give pickup animations) into real items
• Thrown items came straight back: items thrown by a player were merged right away and could be picked back up almost at once.
• Reserved items became public: items only one player may pick up (/give with a full inventory) could merge into public stacks.
• Stale labels: the "x64" label didn't update when a player or hopper took part of a stack.
• Cleanup missed some drops: it ignored items above y=320 and below y=-64.
• Cleanup spam: a SimpleClumps_CleanupMinutes of 0 or less ran the cleanup and its chat message every tick.
• Config:
  • A malformed config file crashed the server on start.
  • Keys missing from the file were never added back.
  • Values weren't validated.
• Tree cutter:
  • The first log counted twice: an extra point of axe damage and a "mined air" stat.
  • It kept chopping after the axe broke.
  • It gave drops in creative mode.
  • It ignored spawn protection and claim/protection mods.
  • It left branches that only touch diagonally (acacia, dark oak, cherry, jungle) floating.
  • Leaves placed by players made log builds count as trees.
  • The tree search had no size limit (could freeze the server on large log builds) and could load chunks.
• Old world's drops processed: queued drops weren't cleared when the server stopped (reopening a singleplayer world).
• License missing from the jar: build.gradle pointed at LICENSE.txt, which doesn't exist.

Changed

• Item merging follows vanilla's rules, over the configured radius:
  • Items merge into the existing stacks, so stacks stay where they are.
  • Smaller stacks go into bigger ones.
  • A merged stack keeps the newer despawn timer.
  • Fresh drops wait until they can be picked up.
• XP orbs are stacked the way vanilla does it. For example, 30 orbs of 2,477 XP become one entity.
• Each log is broken like a normal player break: tool damage, enchantments, stats, creative and adventure mode, protection mods.
• Large trees are left alone: trees with more than 256 logs are skipped.
• Tree detection only counts naturally grown leaves.
• SimpleClumps_CleanupMinutes: 0 turns the scheduled cleanup off.
• Invalid config values are replaced with safe values in memory, with a warning (radius at least 1, minutes at least 0). The file itself is never overwritten while it can't be read.
• README: corrected the radius description and documented the cleanup and every config option.
