For level 5 - Stick the 6g corner in the left side. then put the 10g in the right one. then make a line with the 20g one in the right side to give 3g on one side and 6g on the other. solved.
Several noticable bugs plague the game. If after battle you press the go button, there is a chance that if you are attacked before the button resets, a new go button will appear befor the battle and let you skip the battle completely.
Hint for some of you: injured people on the road will join you if you take them to town, so fill out your crew with guys you find on the road. One of mine had fours in all categories except trade. Leave a spot open while you are creaing your crew and if you don't like the one you pickup, fire him and try again later. A crew of 5 all with highest sword and armor will kill everything except some towns. To capture a town, select battle at the entrance instead of enter, but be aware of health because even with highest gear it can hit in the 30s per hit and sometimes 40.
Problem is that you start where the 3 is listed in your layout. [2, 2, 1, 2, 2, 2, 2], [1, 2, 1, 2, 1, 1, 2], [1, 2, 2, 3, 2, 1, 2], [1, 1, 1, 1, 2, 2, 2], [2, 2, 2, 2, 2, 2, 2], [2, 2, 1, 1, 1, 1, 2], [1, 2, 2, 2, 2, 2, 2]];
Having it there means any direction you go you can't get to rest of the squares. If however you started one to the right so it would be [1, 2, 2, 2, 3, 1, 2] then it would work fine.
