Hi,

game ask me all the time to build a district, but how cause im forced to fight all the time.

Those free cities attack me all the time with overpowered armies. No fun at all. 

All i have now is an invisible hoplit lol.

You should save your current turn and reload it, that will fix the "invisble unit" bug. FYI, it is a known bug among others : Known issues

About the "free cities", called Independent People ingame, there are two kinds : 

- the ones with a lightning are violent, which means their units will attack any unit on sight (regardless of the player). They won't attack your cities, so unless you outnumber them and/or if your armies are stronger, it is better to keep your units inside your cities until you can grow armies that will be able to fight them back.

- the other type is peacefull (with a peace symbol), they will only wander around the map without attacking first.

You don't need to reload to fix the invisible army.

Firstly, it looks like it happens from a preview of the combat but then no combat happens if you decide to move somewhere else. So to prevent it try to move more carefully.

But in case it still happens:

All you have to do is move 1 unit out of the army to a new space - it will be visible. Then merge the rest of the army into the new army, and it will stay visible.
