Game.LoadGame 反射构建 Yaku 时并未排除 SpecialYaku 基类

[lxyunclebill]

Game.LoadGame 中这段代码

var yakuTypes = Array.FindAll(types, t => t.IsSubclassOf(typeof(Yaku)));

取得的 yakuTypes 会包含 abstract class SpecialYaku，导致 yakuTypes[i].GetConstructor(Type.EmptyTypes).Invoke(null) throw nullException

建议改为

var yakuTypes = Array.FindAll(types, t => t.IsSubclassOf(typeof(Yaku)) && t != typeof(SpecialYaku));
