Leenaquu

So my brother is hosting multipayer and i was playing in his server and everything was fine until i placed objects/blocks and they vanished. But after that i could still play but i always have to have more than 1 of same objects in my inventory so i could place objects. After playing while i got another bug and only thing i could do is moving ( i couldnt choose objects, place them or anything.) I restarted game and then tryied to re join the server and got stuck at 100%. After that i have not been able to play the game anymore. My brother is hosting server and he can join the game but he cant do anything also. Please fix this!! We cant play this game anymore if you guys dont give us new multiplayer update!

Same problem
