0.8.3.1 - Bugfix update

A few bugs slipped by my testing, teaching me once again not to do last minute changes before an update. Here comes the first bugfix patch: 0.8.3.1:

• Fixed an issue that would sometimes prevent villagers from harvesting silver from mines.

• Building farms via click-and-drag now works even when far away from the starting town hall.

Thanks for helping me test so far! I'll keep testing and patching issues while I work on the next update. /Andreas
