Corrupted game file stops 1st strike combat in 1914 NML

An online team game of Domination 1914 NML has become corrupted and no longer performs first strike during combat. Subs and gas no longer roll first and separately from other units, but jointly, and resulting hit units fire back. Gas continues to fire every round. Also, computer doesn’t ask for bombardment. A player must have a corrupted game file, which continues into subsequent player rounds. There is no setup setting that asks to turn on or off first strike capability. Can’t over-ride/reverse it. Editing every move/change from the last good round onto clean file isn’t practical. Modifying every future combat affected by this will be tedious. Prefer not to abort the game. The debug pull down menu in the game has code, but nothing appears obvious. Help

@barnee Thanks. Turns out one team player was using an ancient version of Triplea engine. We’ll just have to manually adjust for the few land battles that use gas. Most players will build DD’s making first strike less relevant.
