Hi,
I think this is right place since this is a tool - I have created Docker image to create x64 AppImage package from latest sources. Maybe someone will find it handy.
Since I'm not allowed to post external links, you can find it on [github]/johnykvsky/openxcom-appimage
In Download section of OpenXcom webpage AppImage linux builds are from 2021 due to Travis limitations - this is why I came up with this Docker image, to be able to easily get latest build for Linux.
Pretty easy, just run docker, execute build script and wait a while, done. Oh, one thing - you need your transifex api token. I don't know if there is public one available that I can use, so I registered there and used my own token.
