@Umbra: I also started a campaign with the Georgians and your mini-mod in VH/VH to be able to test your new units.
First of all, congratulations on your work on the units. I also saw that you worked on a lot of files other than those dedicated to the appearance of the units and this shows that you have a more extensive level of knowledge of the game files than me.
My campaign with your mini mod was different from yours (although I only got to turn 38) and I haven't yet exploited the mines in Ani. This will undoubtedly be useful advice from you if I survive the simultaneous attacks of ERE and the Cumans.
ERE refused from the start any diplomatic agreement. I did not attack Trézibonde. ERE landed with a first army by surprise and returned again after being pushed back twice.
I tried several times to have an alliance with the Cumans, until offering them 2000 florins and map information. They refused all the time and are now launching raids on my territory at the same time as ERE.
When I was besieging Bab al-Abwab, bad luck would have it that a jihad was launched on this city. I had just enough time to take and pillage then flee to Baku before the arrival of the Muslim armies! I would have been unable to resist them.
