I just checked all 4 of the 2.2 installation packages on my hard drive. These are the
master files. In other words, the files that were uploaded to all mirrors. The date for wq3_pak3.pk3 is 2006-11-20 in all 4 packages & wq3_pak4.pk3 is not included in any of them. I ran a test install with the wq3_b22_full.exe and looked at the files. Everything is normal. Then I ran the wq3_b22_update.exe and checked again. Everything is still normal. Anyone who performs a fresh install of 2.2 with the exe should have nothing more (and nothing less) than what you see in the screenshot below. Of course, the fan maps would need to be installed afterwards.
Since Gentleman is part of the Kowboj community and Don Antonio has access to test files, I speculate he obtained the test files from there. Uninstalling WQ3 will not remove any extra files in the directory. (wq_nonamecity.pk3 for example.) To perform a true fresh install you would need to delete an existing westernq3 directory before installing.
Maybe Don A should think about removing outdated files from his website to avoid more problems like this. If anyone finds an official installation package with incorrect files please let us know so we can contact the host & get it corrected.
