confirm it looks like to work

- In my opinion it would be better to add alot bugfixes, before adding new stuff like gamemodes
- Matchmaking? Will you be able to pick a tribe?, or will it be decided by the order of joining the server?
- The waterfall has alot potential, plz don't waist him on something like that.
- When talking about water: I'm hoping for lakes with the size of a maddow, 2-4 each map.
for fishing and to take water as an alternative for clouds as merc23 suggested above.
Additionally it would be awesome to be able to see how many fish are still in a lake. 
And just for the lol, rare goldfish that give gold instad of food. and to make the nice to have complete an posibility to spend 1 food to invest in fishfarming, like planting something.

I'm against that suggestion. As you already pointing out this will cause conflics.
It's already hard enought to get people build together.
I would rather suggest an pool of names depending on the kind of Tribe.
or someting like:  "adjectives" + "tribecolor" + noun or even more generated

It's not pointless. Theres a valide point of thinking about smart starting positions.

An easy fix (only for the castle mode) would be spawning on the map edges, but even there somebody could have build an castle. So it might be the best to add some kind of condition to check if an allied castle exists, where you could spawn safe..Maybe under the castle name.

Happened to me more then 10 times. Is not PC hardware related.

I just deleted the cashe and saw it.
