# Bug fixes.

- Fixed a crash that was happening in pathfinding on maps where some
tiles had invalid texture names (from earlier versions of the game).
- Releasing the mouse over the minimap while dragging a selection band
will no longer cause the view to move there. Unfortunately, the bandbox
still won't properly "release". The bandbox input routine should ideally
be placed at a higher priority than the GUI, separate from the other
Interact.cpp routines.

This was SVN commit r4711.
