Hello @rsud_1
Hmmmmm, well I think your errors show on line #623-624 that the server loaded.
If you created a new level, named Level_01, and left the oold level_01 in there… You may have both, and should most likily just rename your level to level_02 and update the links (the editor to load level 02, the menu to have level_02 ect.)
You may have two level_01 in your game, which could cause this confusion?
Additionally, that error often means “Hey, we are loading this item, but its not the EXACT SAME as the server - you prolly need to rebuild everthing at the same time” or “hey, we are trying to load this item, but cant find it… aka you didn’t compile with it or its not in the item registery”
Did you add anything besides the level, like movable objects ect? If you are using more items in the FPS sample, you may have wondered into registery issues. If you hit “prepaire registeries” that can resolve it.
I think its in the FPS-Sample menu under registeries.
Get everything compiled, no name conflicts, and registered… should remove null references (refferences to null or nothing)
Also, like the video says, this assumes you used GIT LFS and downloadeded the whole project. If you use any other menthod, like Git Clone from the website, you ARE missing vital files which were not downloaded, and that IS causing this issue.
