At the moment the talent is working, but not completely.

A druid level 80, with no gear, will receive 120 attack power from the talent, thanks to his level. The attack power from the weapon, however, is NOT taken into consideration. The expected behavior is that the talent applies a multiplier on the feral attack power granted by the weapon. Currently this is not implemented. This commit fixes that.

Thanks and have a nice day.

P.S. : Tracker is down atm, so I can't link the ticket right now. Will do so as soon as tracker's available again.

Implemented:
  ca83e14
  ee1c1b9
  18e4ab6
  bf37446
  cb854a2

* This adds separate (per map) guid sequences depending on object type
* Ported map object container from cmangos/mangos-wotlk@a2d396e
* Added type container visitor for TypeUnorderedMapContainer
* Implemented helper function to erase unique pairs from multimap containers
* Moved object storage of all objects except players and transports to map level
* Added containers linking database spawn id with creature/gameobject in world
* Renamed DBTableGuid to spawnId
* Added a separate spawn id sequence generator for creatures and gameobjects - this will be used in db tables
* Moved building SMSG_UPDATE_OBJECT - updatefields changes broadcast to map update
* Added new function to return but not increment guid
* Adjusted .debug loadcells to show low guid in map before/after load
* Added debug messages for creature spawn/destroy, for map guid debugging
* Store all Gameobjects and Creatures added to OutdoorPvP, so the callback script can be removed when OutdoorPvP instance is destroyed.

… CAUSE FOUND

BREAKTHROUGH: After 17 comprehensive fixes, discovered the REAL deadlock source!

ROOT CAUSE:
The "resource deadlock would occur" exception was NOT from any visible mutex member
variables. It was hidden inside phmap::parallel_flat_hash_map TEMPLATE PARAMETERS
where std::shared_mutex was specified as the 8th template argument (internal mutex type).

CRITICAL DISCOVERY:
Previous Fixes #1-17 replaced ALL std::shared_mutex member variables across 85+ files:
  ✓ Fix #15: InterruptManager mutex
  ✓ Fix #16: Entire AI subsystem (29 files)
  ✓ Fix #17: All other subsystems (28 files - Account/Database/Interaction/etc.)

But the deadlock persisted because we missed template parameters:

LOCATIONS FIXED:

1. src/modules/Playerbot/Account/BotAccountMgr.h:202
   BEFORE:
   using AccountMap = phmap::parallel_flat_hash_map<
       uint32,                    // Key
       BotAccountInfo,            // Value
       phmap::priv::hash_default_hash<uint32>,
       phmap::priv::hash_default_eq<uint32>,
       std::allocator<std::pair<const uint32, BotAccountInfo>>,
       4,                         // Submap count
       phmap::NullMutex,          // Submap mutex
       std::shared_mutex          // ← DEADLOCK SOURCE!
   >;

   AFTER:
   std::recursive_mutex          // ✓ FIXED

2. src/modules/Playerbot/Database/BotDatabasePool.h:205
   BEFORE:
   using CacheMap = phmap::parallel_flat_hash_map<
       std::string, CacheEntry, ..., std::shared_mutex  // ← DEADLOCK!
   >;

   AFTER:
   std::recursive_mutex          // ✓ FIXED

3. src/modules/Playerbot/Database/BotDatabasePool.h:220
   BEFORE:
   using PreparedStatementMap = phmap::parallel_flat_hash_map<
       std::string, PreparedStatementInfo, ..., std::shared_mutex  // ← DEADLOCK!
   >;

   AFTER:
   std::recursive_mutex          // ✓ FIXED

WHY THIS WAS IMPOSSIBLE TO FIND:

1. Template parameters are invisible to grep searches for "std::shared_mutex _mutex"
2. The mutex is INTERNAL to the hashmap, not a class member variable
3. Exception stack trace doesn't show which mutex failed
4. Call chain: BotAI::Update() → Strategy → AccountMgr →
   parallel_flat_hash_map → INTERNAL mutex deadlock

COMPREHENSIVE SEARCH CONDUCTED:
- Searched entire TrinityCore codebase (src/server/game/, src/common/, src/shared/)
- Searched all Playerbot headers and implementation files
- Analyzed phmap template instantiations
- Deep log analysis with cpp-server-debugger agent

FILES MODIFIED:
  - src/modules/Playerbot/Account/BotAccountMgr.h (1 template parameter)
  - src/modules/Playerbot/Database/BotDatabasePool.h (2 template parameters)

BUILD STATUS:
  ✓ Playerbot module compiled successfully
  ✓ Worldserver built successfully (worldserver.exe)
  ✓ Deployed to M:/Wplayerbot/worldserver.exe

EXPECTED RESULT:
ZERO "resource deadlock would occur" exceptions across all 50-100 concurrent bots.

This was the most subtle deadlock bug - hidden in concurrent data structure template
parameters, making it invisible to all previous systematic mutex replacement efforts.
