I don't know if anyone else needs this, but I did it anyway.
1) The campaign end date has been moved from summer 523 to summer 623
2) Fixed victory conditions not being displayed for all factions where it didn't work before
3) Fixed a missing port in the province of Venta Silurum

A new campaign is required.

All custom events have been removed as a possible source of stable crashes on turn 148 and others

Presumably fixed crash at the end of turn 139 (479 AD winter). A new campaign is required for the fix to take effect.

Fixed game crash when starting a battle with a new unit

New changes:
• Compatible with patch 2.0.4
• Changed the starting positions of the Romano British
• Added a new unit - the first cohort of legionnaires for the Romano British.
• Other minor fixes
In the future, there will be a major update with a new map based on Invasio Barbarorum. I don't know yet if this will be released as an update for the current mod or as a separate modification.
Stay tuned for workshop updates. Thanks everyone.
