I cant install this for some reason? When iam in the main menu of besiege i see the create level thing, in console there is an error: NullReferenceException: object reference not set to an instance of an object
Yep. TC mostly vanished a while back (he very occasionally visits the modding slack), and afaik no one's working on anything like his level editor atm.
If you really need to create & edit levels, your best bet is to probably pick up a (free) copy of VS2015 Community and JustDecompile and recreate the mod yourself, updated for the latest version.
Hi, I just have a little problem with this mod : when I press "Create a new level", it just does nothing at all
EDIT : sorry, i just not took time to read everything, now i know it's not an updated mod for 0.3
