Thank you very much!+rep! It fixed the catapult smoke but, as you said, trebuchet fire missiles still have square smoke. As for the square dust clouds... well, it did'n happen again, even before I applied the fix. But I swear I saw it.
Yes, I have the same problem. Not only his shield, but also his sword have a wrong placed texture.
I started a Cuman campaign and found something that probably isn't a bug, but somehow feels wrong:
I noticed that the missile range of some horse archers has been drastically reduced. Nothing wrong with that if it's done consistently. But looking at the export_descr_units, it turns out that some horse archer units like Cuman Horse Militia, Pechenegs, Magyar Cavalry, Yasi Archers, Aldari Druzhina all have a missile range of 70 (less than peasant archers and archer militia), while Bekh Druzhina (spelled Behk Druzhina in the edu, if you want to look for it), also a HA unit, has a range of 200 (which feels like too much)! For comparison, Lithuanian cavalry, which is a basic unit that can be recruited from the start, has a range of 140. How can it be that basic Lithuanian horse archers have double missile range of Pechenegs or Magyars? I, of course, edited the edu to have more coherent (IMO) values. But I'm still wondering if that was intended or an error.
