问题描述：

我正在为我自己和朋友开发一款用于改善网络连接的模组，但游戏在读取协议层数据时遇到问题，我起初以为这是我模组的问题，直到我用日志尝试定位问题时，发现
服务端：

[12:24:04.313] [Main Thread/INFO] [PublicLogger]: [HookBridge/INFO] Detour.ModPacketSend: mod=ImproveGame netId=40 moduleId=30 moduleType=ImproveGame.Packets.NetAutofisher.RollItemRequest toClient=0 ignoreClient=-1 target=100.124.114.125:50762(Anonymous) len=29 head=1D00FA281E0000006D000000001E000000000000404D1F9E|...(....m...........@M..

客户端：

[12:24:04.472] [Main Thread/WARN] [PublicLogger]: [HookBridge/WARN] Detour.HandleModPacket: drop invalid NetIDs packet reason=modCountOutOfRange side=client-reload(single) reload=True whoAmI=256 peer=100.117.85.52:7777(server) length=27 remaining=131067 modCount=7720 firstByte=40 suspect=unknown previewLen=32 previewHex=281E0000006D000000001E000000000000404D1F9E0100000000070052000000|(....m...........@M.........R...

而这个数据来源于ImproveGame/Content/Tiles/TEAutofisher.cs，如果不拦截这个数据，会导致客户端

[13:13:13.114] [Main Thread/INFO] [StatusText]: The server expects Player.MaxBuffs of 0
but this client reports 143.
Some mod is behaving poorly.
[13:13:13.115] [TCP Client Thread/INFO] [Network]: Closing TcpSocket

因为钓鱼机发送的数据破坏了tModLoader/patches/tModLoader/Terraria/ModLoader/ModNet.cs的NetID，导致服务端与客户端无法正确同步模组数据，随后客户端无法正常连接

如何稳定复现：

在多人服务器放一个正在工作的钓鱼机，确保：有液体、非微光、非松露虫鱼饵、有较高钓鱼力与速度加成（提高触发频率）
有一个正在重载模组的连接客户端（需要重载时间稍微长一些触发钓鱼机发送数据的时机）
复现的完整日志文件：

server.bak.log

client.bak.log
关键点位于：

会不会是给出日志中其它模组的问题？

并不是，因为给出的关键点中，其它模组发送的是广播消息，而广播中并不包含正在重载模组的客户端，而ImproveGame直接发送到了100.124.114.125:56940(Anonymous)也就是还未进入到世界当中的客户端，导致tML状态机被破坏从而引发一系列异常，最后客户端强制断开连接。在我查看到ImproveGame\Packets\NetAutofisher\RollItemRequest.cs中的summary时，发现提到

/// <summary>
/// 服务器发送给任意连接的客户端，询问钓鱼机“假人”所处环境
/// Player.UpdateBiomes本应是客户端执行的代码，不应该放到服务器运行
/// </summary>

也许给任意连接的客户端发送消息是很糟糕的行为

如何尝试修复？

请使用Main.ActivePlayers而不是Main.player来获取活跃客户端
