fix: open the mail picker before skin lookups finish - #28
Conversation
The picker waited for RPCharacters to fetch every uncached character skin from ProvinceSystem, one request at a time, before it opened. On Main this can take minutes. Players who retried in the meantime lost their first letter, and each extra refresh later opened a picker over the current one, which cancelled the session so the next click (such as Next) closed the menu. Open the picker straight away with the cached skins and redraw the heads when the refresh finishes. Only open a picker while a letter is waiting and none is already showing. Return any waiting letter before a new one replaces it, and make the delayed close after placing a letter close only the letter GUI.

Merge Risk: 🔵 Low · up to The picker refresh is largely corrected, but visible refresh coverage and selection pagination should be addressed as bounded follow-up risks. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new flow has safeguards against replacing a pending letter, reopening an old picker, and sending to a recipient who is no longer valid. One callback scheduling guarantee remains unverified, so the risk cannot be treated as minimal. Retained concerns

session.getSelected() against the refreshed targets by owner UUID and character
ID. Clear the selection if it is no longer listed; otherwise update it to the
refreshed target and set the picker page to that target’s new index. When there
is no selection, preserve the existing page-clamping behavior before applying
the page.

Compare the open inventory with the one that scheduled the delayed close, so a new letter GUI opened in the meantime stays open. Drop a picker selection whose recipient disappears when the heads refresh. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

When
targetsis empty, update the picker, clear the selection, reset the page, and redraw it before returning. The current return leaves stale targets and selection visible. Confirmation can pass the stale target totrySend, butMailService.trySendrejects recipients that are no longer listed and returns the letter. The impact is a stale picker and a failed confirmation, not a send to the removed recipient.Suggested fix
if (targets.isEmpty()) { + picker.setTargets(targets); + session.setSelected(null); + session.setPickerPage(0); + CharacterPickerGui.applyPage(session, picker); return; }🤖 Prompt for AI Agents

Problem
Bug report: after putting a letter in the mailbox, the recipient picker can take several minutes to appear. Pressing Next can close it, and a new picker can then appear minutes later.
openPickerwaited forRPCharacters.refreshMailTargetTexturesAsyncbefore it opened anything. That refresh fetches each uncached character skin from ProvinceSystem one at a time, with an 8 s timeout. Main has about 240 characters and its log shows wardrobe requests timing out, so the wait can run to minutes.While nothing showed, players retried:
Changes
refreshPickerHeadsredraws the heads if that picker is still open, keeping the page and selection.TF-Minecraft/RPCharacters companion PR: stop repeating failed skin lookups on every open, and let overlapping refreshes share one. The two PRs don't depend on each other: this one works with the RPCharacters build already deployed.
Testing
PickerOpenTest: the picker opens before the refresh finishes and is redrawn afterwards; a closed picker is left alone; no picker opens without a waiting letter or over one already showing. It fails onmainand passes here.mvn verifypasses.🤖 Generated with Claude Code
