I'm using the Ultima SDK...
Any ideas?

ya thats not really a bug so much as it is a fix in 2.0

in StringList.cs it says sometihng like

while(bin.PeekChar())

needs to be

while (bin.BaseStream.Position != bin.BaseStream.Length)

that'll fix it

I love you.

The funny thing with this issue is it produces on low ram systems, so it's rather difficult to catch it.

Try to launch Razor or Pandora's box (last version) on a box with 128 MB RAM, you'll get this exception.

Opening the file with ASCII encoding instead of utf8 also seems to fix the problem. Since the actual contents are read as bytes by uosdk the encoding won't matter, but it will allow the peekchar to not overflow.
