First my found bugs:

1.) The game has crashed and now when i try to load the save game, i get an error msg during the loading screen, and the game crashes again.

    I was finally in the endphase of that game but now the save data is lost.

2.) If you play with a lot of monsters at start it s pointless, because monsters are too strong and the heroes and units are way to weak.

     e.g you have 70atk/30def (unit) and the monster has 50atk/20def you do only 5 dmg and the monster 18 to 25 dmg. With that a unit dies way

           to fast.(that was a mid lvl unit, with low lvl ones you have no change against trolls, because that are one hit kills)

3.) not sure if its a bug, but the MAUL skill on a weapon is to strong monster with 250 hp kill in one round from my lvl 25 hero with 13 hits ranging

     from 10 to 30(critical).

Then some suggestions:

1.) Trading caravans are shown under active units. Pls make it that only units that are waiting for an order are shown there and not all your caravans.

    I had 20 or more running and with that it was hard to find armies or units that were waiting for orders.

2.) Pls make it possible that you can use your trade route roads in your country to move units faster through your empire.

    Maybe even implent engineers that can upgrade important roads faster. (Road is implanted from the caravans and you can send an engineer there so the trade route lvls up faster).

3.) Upgrading from units: a.) make the money needed for that lower, e.g.: 20k to upgrade armor for a unit is way to high.

                               or    b.) make it that you can upgrade the units in town over the workforce of your empire.

4.) It s nice to buy weapons for your heroes, but it would be even nicer to craft them for yourself (costs: money, rescources, and special magic items)
