Ok, a number of questions here. First, why are you loading the tutorial?
Second, are you sure the dedicated server was the last thing you tried to use before posting your console.log file?
Third, what is gaara sama and why is it trying to replace the MissionInfo?
Error: cannot change namespace parent linkage for MissionInfo from ScriptObject to gaara sama.
You've got a lot of fishy things going on there, not to mention a lot of crappy mods installed like the decollisioner. If you're really eager to get a dedicated server going, the best solution I can suggest is to reinstall Blockland and ONLY download add-ons that work well, like JVS Doors for example.
