So I just made a new tekkit lite server. Everything seems to be working fine, except no one can place any modded blocks or anything. We can use regular minecraft stuff though.
For example: if I go and select a nuke and put it in my inventory. I can see it in my inventory, but as soon as I try to place it, it doesn't seem to want to place and it disappears from my inventory.
Any advice to help me fix this greatly appreciated. Thanks!
