Thread:Extension talk:Maps/Error with Mapsize/reply

Can you try running the latest svn trunk code for both Maps and Validator (the version should say 0.6.4 a5) and see if you still encounter this issue? Someone already reported this, but I have never been able to reproduce the issue, so am unsure if it's currently fixed or not.

Note: if you don't know how to get the svn trunk code, just give me a poke and I'll do an export for you.
