textures not loading first time is a classic unreal thing, will be fixed in next version.
dotted lines and falling through the floor a bugs that will be fixed.
The durability will play a big role but currently it's not really implemented, you will be able to get a repaired shotgun.
Sorry for the bad tutorial, it was all thrown together in haste.
the randomizer is currently awful, in future updates you won't be able to get the same course twice.
Thanks for playing and for the feedback!
