Picking hero crashes map

So, in my map, there is a hero called the Felblade. He is purchased at a Tavern. However, whenever the Hero is picked it crashes the game without an error message...

There are no triggers involving him at the start of the map.

Any ideas on how to prevent this?

How does your hero selection system work? Is he created in a place that can affect other things, for example in a region that has 'a unit enters region' events? It can also be the model being bugged. Please give us more details.

Hmm, odd. You're right (hang on I'll explain what about :P), it was a bugged model. Well, whatever, dont need it. Uh, thanks.
