levels

[(Akshay Srinivasan)]

I put in 500 levels and a player got to level 130 then wierd things started
happening to his char.  He would log off and it would give some garbled output.
When I looked in his file it seemed ok but when he logs on again he comes up
with level -126 and hp 0/0, very annoying as anything and everything kills him
instantaneously.  Anyone seen this or could think of how this could be happening
I thought exp was a long and hopefully saved as such in which case it should not
have much trouble with large numbers but obviously saving and retrieving them
seems to be a problem.  Is this why levels was limited to 100?

Thanks in advancem,
Akshay
