/give command doesnt work + Cuboid, +Houses Dissapearing?

[Mylo104]

Ok guys i have a problem.So yesterday i was running Hmod Build 135 but i found out that 137 was out so i cleared all of my Build 135 files out and put my 137 Build files in.Now, on 135 i could always do this:/give wood 5 , but now on 137 whenever i do /give wood 5 it says unkown command.So now i have to do this : /#give mylo104 5 5 And this is nto fun for me. Also another problem i have is Cuboid i installed it for Build 132+ and whenever i right click with a wooden shove it doesnt say anthing.Also this is a very weird thing that happend to me, i was in my server with a buddy of mine we went mining and some other player said that the house was gone so i went back to the surface and saw 2 of my friends' house's dissapeared , But i had to repaire them.Anways could anyone help with these problems thanks ! :)
