[MADHOUSE]

Hey all ;
We fixed it on our end! This may or may not work for others

• First we took the game level wich only consists of a couple actors, a few dozen meshes and a postprocess volume then he rebuilt it by creating an empty level and drag dropping everything back in.

-More importantly we went to
Project Settings > Packaging > List of Maps to Include in a package build > + And added all our levels that where in our persistant level. Basically all the levels for the whole game.

Not only did this reduce the packaged build size by about 1 gigabyte but also the error and crash are now gone

Hopefully this helps some peoples.
Good luck all

Hmm no difference over here. Not using any level streaming tho since our project is a multiplayer game, only servertravel loads.
I created new levels and pasted in the actors from the old ones and rewrote all levels in the entire project, and all levels are added and setup in the map list as well as in the config files.
Sill crashes

Sometimes the crash looks like this as well:

EDIT: All servertravel crashes seems to be gone in 4.17 preview 3. Still looking into it tho.
