Hello, first post!

I'm playing Pahlava on H/VH and down to 215 B.C.E. I've gotten 90% of Arche Seleukia, most of Baktria, and the Levant.

I take Chach from the Baktrians and send some armoured HA down to Alexandropolis to reinforce the garrison against seige. Attacking a mercenary army led by a FM, I am quite puzzled to see that the interface has reverted to something that looks like Shogun and Medieval I.

I haven't figured out how to fix it with search engines and documentation. Any ideas?
