Hey there, We have updated the server to 1.12 and you are no longer able to join with older clients. Please make sure you are using the latest release (MC-1.12) to keep playing on BuildCraftia! So many new things to try and experience in 1.12; new colorful blocks, new mobs and much much more. We are planning to use these new features more thoroughly sooner or later. Since the game version is so new, there will be bugs and we need your help finding these bugs. If something is not working at all or it is acting different than before, please let us know! You can submit a bug report on the appropriate forum under “Bugs & Suggestions”. We aware that the tab is not as it used to be before. There were some problems we could not fix as of yet, and we are investigating the problem.
