I deeply apologize guys. Alpha.19 had a critical bug that was causing combat to crash. I fixed this. Also, someone was having trouble loading a previous save? I added some sanity checks to prevent load failures.
I also forgot to mention in the vAlpha.19 update that female characters were added.

非常抱歉，各位。Alpha.19 版本中存在一个严重错误，导致战斗时游戏崩溃。我已经修复了这个问题。
另外，有人遇到了加载之前存档的问题吗？我添加了一些完整性检查来防止加载失败。
我还忘了在 Alpha.19 版本更新中提到，已经添加了女性角色。

1. New Active Quests Banner: A handy new feature to help you manage your quests! Alerts and step-by-step guidance will ensure you’re always on track. You can now click a banner in the top-left corner to view your current active quest lines and plan your next moves easily.

2. Level-Up Drop-Down: Gain XP in Knowledge or Combat and enjoy a new visual drop-down that dynamically displays how much XP you’ve earned, making leveling up feel more interactive.

3. Performance Optimization: For both Mandarin and English players, we’ve streamlined runtime mechanics by preloading label widgets. This reduces the need to open large .ttf files during gameplay, ensuring smoother and faster performance.

4. Faster Startup Times: We’ve transitioned from a single .exe file to a directory-based system. While this results in a larger game size and a bigger update to download, it significantly reduces startup costs, so you can dive into the game more quickly. Let us know if this change improves your experience!

5. Bug Fixes: Hidden Lair issues at high classes have been resolved, NPC attack mechanics at higher combat difficulties have been corrected, and crashes caused by loading a previous Mandarin build into English have been addressed with additional sanity checks. We’ve also squashed a few smaller bugs to make the game more stable.
