@JPatrickRemiger since you’re new to triplea, might as well start out with the latest https://www.axisandallies.org/forums/topic/39809/new-triplea-map-uhd-world-war-ii-global?page=1
can only DL with 2.5. Otherwise gotta go direct from git.
you can have 2.5, which works in the lobby, and the prerelease both installed. The prerelease won’t work with 2.5, so switch back and forth if using a save from the prerelease and lobby games.
