I've spent a couple hundred hours on a custom campaign and a good chunk of that time was spent replaying it over and over due to the requirement to beat it before publishing. Without failure, one of the levels always crashes when going through a level transition after beating it.
There's not a lot of objects or enemies in each floor and the levels work flawlessly when played outside of the campaign. Is there a way to publish a campaign without needing to dump hours into playing it?
