--- Comment #12 from William wjb@williamjbowman.com --- Reproduced on wine 6.21. It's actually unnecessary to install the patches to reproduce the bug. 1. Install the client by running `wine ClassicConquerInstaller_1010.exe` 2. Press "Start Classic Conquer" at the end of the install. 3. Press "Play" on the launcher, ignoring the fact that it hasn't finished patching.
