+如果你希望在 QQ 群中反馈问题，请[赞助 HMCL](https://afdian.net/@huanghongxun) 后申请加入群聊，也请将下面的信息表填好直接发在群中，加快我们的沟通速度。
+
+
+
+# 问题提交
+
+*完整地填下面的问题提交表对我们很重要，这可以加快我们分析问题原因的速度。*
+
+* 启动器版本：
+* 操作系统：
+* Java 版本：
+* 错误截图（最好请将整个电脑屏幕的截图发上来）：
+* 游戏版本（如果是启动通过启动器自带的自动安装功能安装的游戏）：
+* 对游戏做的修改（是否自行通过安装器安装 Rift 等 API，以及 mod）：
+* 游戏崩溃报告（如果有）：
+* 启动器崩溃报告（如果有）：
+* 启动器日志文件（出现问题后点击启动器设置中的【导出启动器日志】按钮）：
