1.6.4 Annihilator's Flamethrower bug

[Zimos]

If you use Mouse to target with flamethrower it does not attack in a cone instead only hits the target twice and nothing else.

[MIC132]

As a related bug, when using boltgun and mouse-clicking to attack the character will move closer if the target is out of your steamgun range but still in boltgun range. (Boltgun has range 10 regardless of your steamgun range). Manually using the talent allows to shoot normally at full range.
