Hello, i am having an issue with my Attack of the B Team Hamachi server. I have created the server and the mod pack works fine in the sense that people can join and play. However, with the new block added with the mod pack there has been issues, (I tested and discovered this whilst in creative upon first joining the game) if the block isn't included in vanilla Minecraft then when going to place it it vanishes and if the block is in vanilla but is an alteration it just places the original vanilla block. Like i said i was using creative so i spawned the block in through the creative menus. Does anyone know of this issue or even better a solution to it. Thank you for taking the time to read this, any help is appreciated.
