--- Comment #2 from [e-mail] ---
A new version of the tar file containing the Battle of Britain binaries has
been released, thus the link to the tar file has changed.  To download the
tar.gz file containing the Battle of Britain binaries, search on "esports for
engineers" at github.

This bug still occurs with the latest versions of Ubuntu and wine, namely
Ubuntu 21.04 and winehq-staging 6.11

Please look at this bug.
