1.3 Broken Save?

[San0ix]

I cannot load my Temporal Warden anymore (http://te4.org/characters/38290/tome/3c ... 3d402c53b0)
This happened in the second level Reknor, after I had some weird performance issues where every turn would take forever to load
Whenever I try to load this save (others work normally) the game gets stuck at 100% and starts flashing

I can load my game when I switch to Minimalist UI but it's weird that I had no problems with 1.3 until now... and I really don't want to play with the Minimalist UI
