Describe the Bug

Hello,

I have found a crash in WoW Classic (Wrath Classic) that seems to be triggered by AllTheThings (ATT) in combination with Atlas.

Environment:

WoW Classic (Wrath Classic) 3.80.0.64393

Windows 10 x64

AllTheThings version: 4.7.6

Suggested fix:

ATT could safely skip or ignore items that no longer exist on the server to prevent client crashes.

Thank you for looking into this!

Steps to Reproduce

Steps to reproduce:

Enable AllTheThings.

Open Atlas and navigate to a dungeon/raid loot table.

Scroll to items that no longer exist on the Titan WotLK server (they still appear in Atlas's loot list but are missing on the server).

Observed behavior:

When the mouse hovers over these missing items in the Atlas loot list, the client crashes.

Crash report shows an ACCESS_VIOLATION in WowClassic.exe.

Example crash summary:

The memory could not be "read".
(DBG-OPTIONS<FunctionsOnly SingleLine> DBG-ADDR<00007ff7be1146b1>("WowClassic.exe") <- DBG-ADDR<00007ff7c00d8498>("WowClassic.exe") <- DBG-ADDR<00007ff7c00cd9ac>("WowClassic.exe") DBG-OPTIONS<>)

Additional information:

Disabling ATT prevents the crash.

The issue seems to happen because Atlas still includes items that the Titan WotLK server has removed. ATT attempts to scan all items in the list, including these missing ones, which triggers the crash.
