Error exporting recipes with Minetweaker

[Former user]

Hi Binnie

When trying to use the /minetweaker recipes command to export a list of all recipes in my mod pack I get an unknown error in my chat log. I've managed to narrow this down to your mod version 2.0-pre1.

I've also posted this on Minetweakers forum but I have no idea if this is something they can fix or not so thought I'd post it here as well

Do you have any more info, apart from that?

Sorry, I thought pre1 was the latest version, just tried it with pre4 and it works ok
