Comment 19 for bug 1651561

Post #17 is a good solution for me - for some reason the file size is different when installing in newer versions, weird. So to test, I used a thumbdrive to run a live 16.04 session, installed Openarena in the live session, and then copied the IOQUAKE3 file to my harddrive. Fired up 18.04 and it works fine.
