【炉石传说国服】掉线重连修复补丁，修复游戏结算（斩杀对手或对手投降）时，掉线重连失败后游戏卡死的问题（基于修改Assembly-CSharp.dll）
打开炉石安装目录（如D:\Program Files\Hearthstone\Hearthstone_Data\Managed），解压并替换Assembly-CSharp.dll文件后，重启游戏即可。
查看Player.log可知，游戏卡死是由于客户端和游戏服务端重连失败导致。
日志中提示的字符串你的游戏与暴雪战网服务断开连接。你可以尝试再次启动游戏来重新连接。对应GLOBAL_ERROR_NETWORK_LOST_GAME_CONNECTION。

使用dnSpy反编译Assembly-CSharp.dll，搜索GLOBAL_ERROR_NETWORK_LOST_GAME_CONNECTION，其中ReconnectMgr.OnGameReconnectTimeout有引用:
分析代码可知，如果当前游戏场景为Gameplay，弹出断开连接的提示后，函数直接return。
而AttemptToRestoreGameState实际上会调用gameMgr.FindGame用现有参数连接游戏，失败则弹出GLOBAL_RECONNECT_TIMEOUT 无法重新连接到游戏。
去除return，走到AttemptToRestoreGameState分支。
由于对局服务器实际上已关闭，故连接必然失败，从而回到主菜单，而不是游戏卡死，导致重开后卡门（排队 > 15分钟）。
