I would like to use authblk in a tikzposter documentclass, together with custom footnodes like in this post: Custom footnotes in the authblk package
Changing the documentclass as in the following code leads to the symbols ∗ and † being replaced by the numbers 3 and 34. To me this looks like some symbols are defined in a different way in tikzposters, but I don't know how to change this. I would be happy for any help.
\documentclass[25pt, a0paper, landscape]{tikzposter}
\usepackage[affil-it]{authblk}
\usepackage[english]{babel}
\usepackage{blindtext}
\title{An efficient method for exploiting midichlorians}
\author[1,2]{Darth Vader\footnote{Contributed equally.}}
% The order may be wrong on these next two:
\newcommand\CoAuthorMark{\footnotemark[\arabic{footnote}]} % get the current value
\author[2,3]{Darth Sidious\protect\CoAuthorMark
\thanks{Electronic address: \texttt{palpatine@empire.gove}; Corresponding author}}
