says that if you use one EUD trigger in Remastered, you get a defeat screen.
One of the users there says
Using EUD triggers will do two major hindrances:
Cannot save/load the game since it’s altering the game’s (map’s) memory state.
Unable to achieve victory screen since EUD triggers are a form of “cheating.”
This also means you will NEVER be able to use the Set Next Scenario action trigger, which is a big hindrance for anyone trying to make a custom campaign with EUD triggers.
Could this be addressed at some point in the future?
