Optimized the umbrella stand model—now using an umbrella will consume a small amount of durability.

## v1.0.2 — Dimension Teleportation Crash Fix

### 🐛 Fixed: Princess Hold Dimension Teleport Crash

Fixed a server crash issue reported by CurseForge users: When a player in a princess hold jumps into a dimension teleportation portal (such as the Underworld or End), it causes the related players to crash and be unable to rejoin the server, and may prevent the server from shutting down normally.

  • Problem Description**
  • When a player in a princess hold enters a dimension teleportation portal, the riding relationship between the held player and the carrier player is damaged across dimensions
  • The affected players crash when attempting to rejoin the server and cannot reconnect
  • Damaged player data may prevent the server from shutting down normally

  • Fix Solution**
  • Added dimension teleportation event listener (EntityTravelToDimensionEvent) to trigger before entity teleportation
  • When the teleporting player is in a princess hold (as a carrier or passenger), cleanly break the princess hold in advance
  • The carrier player can still pass through the teleportation portal normally, while the held player remains in the original dimension, fundamentally avoiding cross-dimensional damage

### 🔧 Technical Changes

  • Added onEntityTravelToDimension event handler to the MCARomanticExpansion main class
  • Reused CarryRuntime.stopCarryFor to remove the riding relationship, clear the pairing status, and broadcast client synchronization
  • Applies to all dimension teleportation portals (Underworld portal, End portal, and mod dimension portals)

> Note: This fix only prevents new crashes. For damaged player save files (NBT containing a reference to the player's RootVehicle tag), manually edit the corresponding player .dat file to remove this tag, or delete the player data file to allow them to rejoin.

## v1.0.8 — Love Letter System

### ✉ New: Love Letters

A handwritten letter that can be tucked into books and gifts, waiting for its recipient to discover.

  • Writing**
  • Craft with paper, book, and pen
  • Sneak + right-click to open editor, fill in recipient name and message
  • Right-click anytime to read a written letter

  • Hiding & Delivery**
  • Sneak + right-click while holding any item in offhand to hide the letter inside it
  • The host item's appearance remains unchanged—no one can tell it contains a letter
  • Only the recipient will have the letter extracted when using the item; other players use it normally, unaware

  • Reply & Affection**
  • After receiving a letter, click the "Reply" button while reading to write back (on page 2)
  • Reply is written on the same letter item—no new item created, preventing duping
  • After replying, both parties gain +3 affection each
  • Reading without replying does nothing—hearts need answers to grow
  • Replies can be written even if the recipient is offline, but affection only increases when both are online
  • Once replied, the original sender can also extract the letter from the hidden host item to read the reply

### 🏆 New Achievement

| Achievement | Description |
|-------------|-------------|
| Message in a Bottle | Reply to a love letter—two hearts draw closer |

### 🔧 Technical Changes

  • Added LoveLetterItem with NBT storage for recipient, sender (incl. UUID), message, and reply
  • Reply stored as "page 2" on the same item—no new item created
  • Extended LoveLetterSavePacket with isReply field, reusing the same packet for writing and replying
  • Added LoveLetterReplyTrigger achievement trigger
  • Reading UI displays both original letter and reply; shows "Reply" button if not yet replied
  • Hide/extract logic fully preserves reply data
  • Extraction permissions: recipient can extract; after reply, original sender can also extract
  • Affection gain integrated with existing AffectionManager system
The update enables players to hug each other.
