The issues with the server version are not in our control, they are issues in the specific mods that have the error not just in the FTB pack, also in answer to your question "did we even look through the code" No, we did not our team does not have time to look through each mods code to find errors in it this could take days and would be impossible in some cases anyway as the code is closed source. However, many of the issues in the server/game will be fixed in the new release coming soon.
