I turned off the "Cancel Skill When Aiming" feature inside the "Controls" section of the Settings and it seemed to fix the problem. I'll update you guys if it stops working.
Same, but before the bug the turret was getting stuck in my hand and not able to deploy, now that seems to have stopped.
I've just started having this problem today. Any skill I used (turret, drone, hive, chem launcher), I can't aim/deploy which is disastrous in a gun battle.
