Any ideas what is causing this?

Loads up instantly when traveling in PIE

Any ideas? I’m trying to package this for a meetup and this is killing me. The error is very cryptic.

Is it a packaging of the map that is the problem? or an asset? i narrowed the changeset to a bunch of blueprints, unfortunately backing out blueprints multiple changes back does not really work.

4

Well, i got the revision before the one that broke everything, and then redid all of my work expect for the revision that broke everything, and it packages. Would still like to know what the hell happened.

5

I’m having the same issue. Which ever map I try to play it crashes at startup.
