Yes, for some reason, campaigns run without problems with the **NHF 0.10** map editor, but if you try to run third-party multiplayer maps, it crashes. However, if you run it with **NHF 0.9**, everything is fine.
So, either install the previous version of the mod - **NHF 0.86**.
Or, wait for the author of the assembly to add **NHF 0.87** and fix all the bugs associated with it.
