Windmill???

[myclan]

Almost in every turn, the message "windmill“ is displayed above, and the "bugevent manager" error messages are still displaying in most of the turn.

I also found that horse archer have an advantage against heavy footman not only attacking, but also defending. Are they just playing the role which crossbowman used to be?

That's a debugging message I forgot to remove. Fixed.

The 'Windmill' message (and names of other improvements) are harmless, just a debugging message I neglected to remove. 'Bug event manager' messages are different though and need investigating. I'll need your PythonErr.log to solve those, which is only created when you've enable logging and python exceptions.

Yes. I went for a compromise between the 'target first away from cities' mechanic of 1.19 and the Crossbowman-like bonus of the 1.20 beta. Horse Archers have a bonus when attacking or defending against Heavy Footmen, but also suffer a penalty if attacking/defending cities.
