So I ended up ordering the Lost Legions and Krang character expansion from amazon UK, which worked out significantly cheaper than from the US.
I also emailed Wizkids and asked about the issues with shades of Tezla, and they said that they are still willing to send out the replacement parts for all the errors in the expansion so that it will match in properly with the base game. Of course Amazon UK didnt have this pack, and it was murder by post to order it from any other UK vendor - luckily I should be able to get it from my local shop (I wanted to ensure Wizkids would come to the party first)
So yeah,
Played a few fun games of Mage Knights, expansions on the way
all good.
I would still like those PDFs if you can find them slev.
Thanks
