Game version 1.12.2 with Forge latest stable version in 2019. Version segregate enabled.
Mods are copied directly to the folder.
When clicking on the "Auxiliaries" button to check mods, exception occurred leaving a blank list like no mod have installed.

我发现使用外置登录时会自动将验证服务器锁定为HTTPS协议，这极大的提升了安全性。但会使用户连接不上没有升级HTTPS协议的认证服务器

I've been waiting for the Skin managemnet update for a long time, won't you release it? Really need this update.

I installed net core 3.1 on the other computer but when I click on the exe extension nothing happens? Windows 10 64bit on 2 systems.

The self update failed on replacing the file because the origin executive is still running and being protected by Windows.
Strange problem: this failure only happened when the file name doesn't have a space. File name like GBCL.exe, GBCL123.exe will get this problem while GBCL -.exe, GBCL 1.exe won't.
It also means 3.11 still have to be download manually or manually replacing the file and rename it.
Maybe you can write a tip on the next release on the release note XD.

从1.13版本开始格式就已经是：🙄
resourcePacks:["vanilla","file/Diamond War150322.zip","file/VoxelMap Skin §e1.X.X.zip"]
而启动器依然是这种格式存取：😅
resourcePacks:["Diamond War150322.zip","VoxelMap Skin §e1.X.X.zip"]

所以出现无限清空资源包配置的情况

这个问题我第一次接触这个启动器时就发现了，然后自己修改了一下就没管了
但是我很诧异这么久了竟然一直没人提😂

JRE 下载按钮的位置很奇怪地下移并覆盖在下方的复选框上，如下图。

另，可以考虑添加检测系统语言和默认字体？
比如用英文版 Windows 时首次启动运行检测系统语言自动转换为英语，或者非中文版又不是目前已有界面的语言默认倒到英文？
非中日汉语言版本的 Windows 默认字体为 Segoe UI

可以尝试延续V2的一句欢迎语，并且直接留下头像、游戏名之类的。

As I understand it, when downloading different versions, they are all downloaded to the same directory !? Maybe you should add the function of creating other directories? Just when changing the version, you have to switch mods and this is a little annoying! 😤

I forget to add:
Please accept my apologies for my poor English! 😏

There is no scrollbar and it is not possible to scroll down.
This in Launcher Settings:

Self update won't replace the old launcher exe file, and the launcher won't start successfully the second time. Investigating...Perhaps need a new self-update scheme

自动更新不能替换旧启动器可执行文件，并且第二次不能正常打开。正在查找原因，也许要找一种新的自动更新方法。

最新版启动器打不开，双击没有任何反应

.

Can you create a setup that will automatically install all the requirements and the launcher as open source?
I'm very new in this stuff, it may be simple for you, but I'd be grateful if you do.
