R2.0.3 Fixes and improvements — Source of the Nile Digital Edition Steam update #1096382

* Fixed a bug in the mini map which recorded the discovery of the Lost city as Dr.Livingstone and vice versa. * Fixed a bug which prevented pack mounts from wandering off due to a lack of bearers to lead them, if the expedition was in mounted mode. * Fixed a bug in the "2 horses and a bearer fall off a mountain path" which claimed one extra horse if the expedition was in mounted mode. * The explorer's musket can no longer be lost due to disasters unless the expedition is travelling by canoe. * Supplies will no longer be lost through horses and camels wandering off due to a shortage of bearers to lead them. * Improved the "supplies lost" algorithm to give more accurate results.
