Machine Party-Overtime 1.3.1（只更新启动器 / launcher only）

本次只更新启动器，游戏内容一个字节都没变。

⚠️ 已经装好 1.3 的人不用做任何事 —— 主菜单右下角仍然是 v2.1.2+overtime-1.3，1.3.1 和 1.3 能一起玩，不需要全房间同步更新。只有装不上的人才需要下这一版。

• 修复：少数玩家点「启用 Overtime」时必定弹出「游戏正在运行，先完全退出」，但游戏其实根本没开，重启电脑、重装游戏都没用，等于永远装不上。原因是旧版只按进程名判断游戏在不在跑 —— 系统里只要存在任何一个叫 Machine Party.exe 的进程（上次没退干净的残留进程、崩溃后被系统挂住的进程、或者别的目录下一个同名程序），就会被拦下。现在改为直接检查游戏数据包本身有没有被占用，并且只有当同名进程确实位于你选中的那个游戏目录里时才拦截。
• 提示更清楚：真的被占用时，弹窗会直接列出占用进程的 PID 和完整路径，照着去任务管理器结束它就行，不用再猜是什么东西占着。
• 安装日志：修复同一批记录被写进文件两遍、以及每次启动多记一行的问题，日志现在干净可读。
• 界面：右上角多显示一行「安装器」版本号，反馈问题时能一眼说清自己用的是哪一版。

适用游戏版本：Steam v2.1.2
安装后的版本号：v2.1.2+overtime-1.3（不变）

下载 Machine-Party-Overtime-1.3.1.zip，解压后运行启动器即可。

如果你之前是装不上的那一位，麻烦装完回来说一声。要是还不行，点启动器左下角「安装日志」，把里面的内容发上来。

Launcher only — not one byte of game content changed.

⚠️ If you already have 1.3 installed, do nothing. The main menu still reads v2.1.2+overtime-1.3, and 1.3.1 plays with 1.3, so a lobby does not have to update in lockstep. Download this only if the installer refused to work for you.

• Fixed: for a few players, "Enable Overtime" always popped up "The game is running. Fully exit it first" even though the game was closed — and neither rebooting nor reinstalling the game helped, making it impossible to install at all. The old check went purely by process name: any process called Machine Party.exe anywhere on the system (a leftover process that never exited, one Windows kept alive after a crash, or an unrelated program with the same name) would block it. It now checks whether the game's PCK is actually locked, and only treats a same-named process as the game when it really lives inside the game folder you picked.
• Clearer message: when something genuinely is holding the file, the dialog now lists the PID and full path of that process, so you can end it in Task Manager directly.
• Install log: fixed the same batch of lines being written to the file twice, plus one redundant line per launch. The log is readable now.
• UI: the top right corner now also shows an "installer" build number, which makes bug reports much easier to place.

Game version: Steam v2.1.2
Version string after install: v2.1.2+overtime-1.3 (unchanged)

Download Machine-Party-Overtime-1.3.1.zip, unzip, run the launcher.

If the installer used to refuse to work for you, please come back and say whether this fixed it. If it still does not, click "Install log" at the bottom left of the launcher and post what it says.
