V-Gears

On some field maps, two errors happen regarding NPCs and the walkmesh:

• If a NPCs gets out of the walkmesh (for example, by jumping), an error is thrown and the script execution stops, because a triangle ID can't be found. NPCs should be allowed to be out of the walkmesh without throwing this kind of errors.
• When a NPC is moving, sometimes it gets stuck because it hits the border of the walkmesh and it can't continue moving. They should be allowed to continue moving, even if it means not being in a walkmesh triangle.
