Challenge Crashes

Sorry Ozks, but I don't like your version, with the challenges all unlocked and the custom graphics.
So anyway, I downloaded Korath's Portals to Theros full MLv3 version, installed, updated with his latest JOU version, installed all the cardart updates, and everything seems to run fine, EXCEPT certain areas of the challenges. Specifically Challenge 1-2 Vanguard Avatars. The 3rd battle always crashes out on my when it tries to change my deck. I've noticed that other challenges hang up as well, but can't remember exactly which ones.
I never had this problem with CirithUngol's MLv3, and I was able to complete that match, but as I wanted additional cards to use, I had updated beyond his release. Now I find myself torn between wanting to do the challenges, and having cool cards to work with.
Has anyone else had any of these issues? Did I miss something between Portals and Journey? Do I need to install all the version updates? Did something else break the challenges?
Note: At first when that challenge crashed, I used to get an ingame error that said something like 'Challenge:13 Something: 15'. Now it just crashes with Manalink v2.00 Alpha has crashed. If anyone can shine a light on this, I'm open to anything.
*edit* Found another, Magic the Puzzling just hangs. Looking at some of the code for challenge_mode, something doesn't seem right. I'll try to compare it with Cirith's if I can.
