Add "-dedicated" to the end of the Blockland Launcher
Wow your handicapped,
This isn't making one this is hosting one that crashes!
Ok I had this same problem,
I had a bad mod which crashed between 30-60 seconds of starting up,
it was because I put a ; in the wrong place with my script,
If you downloaded a mod and you could host still then don't delete that, if it stopped working after you installed
a mod delete that. Sometimes it can happen with conflicting mods E.G. Slayer and Team death match, when Slayer was first released it conflicted.
