我正在使用 MNRAS 类https://www.ctan.org/tex-archive/macros/latex/contrib/mnras?lang=en，而且我的参考文献的行为非常奇怪。
我正在使用 BibTex，有时文件可以正确编译，有时则不行。例如。我在文本中间有一个表格（带有交叉引用），如果使用：
\begin{table}
\begin{tabular}
\begin{tabular}
\end{table}
代码正确遵循并且所有参考均出现。
如果我更改为带星号的版本：
\begin{table*}
\begin{tabular}
\begin{tabular}
\end{table*}
然后，我的所有参考资料都消失了，并被问号符号取代了！！！
是什么原因造成此情况？
編輯：
\begin{table}
\centering
\caption{My caption}
\label{tab:a}
\begin{tabular}{ccccccc}
%HERE GOES THE TABLE
\end{tabular}
\end{table}
编辑2：
我注意到导致该问题的原因并不是某个特定的表。如果我删除或移动表，就会出现错误：
“pdftex 错误 \pdfendlink 最终位于与 > \pdfstartlink 不同的嵌套级别”
这是我的序言：
