LaTeX3 MOdiagram 包中的错误

Question

我尝试使用MOdiagram包 (38448 (0.2g)) 编译空文档并收到 LaTeX3 错误

! LaTeX3 Error: Variant form 'cNc' deprecated for base form
(LaTeX3)        '\dim_compare:nNnTF'. One should not change an argument from 
(LaTeX3)        type 'n' to type 'c': use a 'v' variant?

TL2018（已更新）。可能是软件包或 LaTeX3 错误。

\documentclass[a4paper,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage{modiagram}

\begin{document}

% Nothing

\end{document}
