From what I can gather there a few possibilities as to what happened:
- A rabid animal aggro'd a visitor who was leaving and when they left it caused a null reference - A rabid animal aggro'd a person who died and was buried (the graves are in the picture to the far left, the two little brown mounds by the water) - this causes a null reference - A rabid animal aggro'd a person who died but hadnt been buried yet causing a null reference
This has all been caused by Null Reference
