So i was just finishing my map that i had used months to create and when i rebuilt the navmesh, saved the scene and restarted all the rendinst dissapeared in thin air
You should always make a copy of the scene. When there are many renders in the scene, when you start the scene you need to give it time to load outside of the editing mode, otherwise you will see the renders visually but will not be able to edit them and if you save them, they will disappear when you restart. If there is no copy, you cannot restore it, I think almost every modder has encountered this case.
Rip:
you got enlisted editor-ed
make sure to tick the backup blk thing.
otherwise many more times this will happen.
however, if that makes you feel better, the three times that happened to me, i ended up remaking the maps better than originally.
Yes, I have lost all my weapon wallbuys (gun+item_in_world+paid_loot_item) way too many times, like 20 times.
Now that you say it, i think if you spawn and despawn animated entities (such as a zombie) too many times without letting the game run, this issue will also occur even if you let everything load in at the beginning
