Oh, cool! Thank you very much!

@AlexHerbert those are the cav you get after Marian reform (Roman upgrade in fort). Once researched, this tech change almost all units of the Romans; It's mostly a tech to make infantry stronger, for cav, stats aren't affected but icon still are. It's new from a27.

@Stan` there is quite few versions of the engine, can you confirm which one to download ? Windows 11 here.
