Server exe runtime crash after scheduled bless castle event

[Phatkone]

Hi Gents (and ladies).

I am finding when I have bless castle scheduled that the server hits a runtime error at the end of the event (and it seems the event doesnt end properly after this).
Although if i manually start the event, it works fine all the way through.

Has anyone come across this that can shed some insight into where I should start looking?

Thanks again
