BUG t2 mobile cybran bomb doesnt stun enemy when it rightclick

In video i shows that mobile bomb doesnt stun enemy when rightclick, but stuns when its ctrl k or killed by enemy. https://youtu.be/j47jsSivSAg Fix it plz.

Let me raise up two more bugs with beetles:

• When told to attack a moving target, beetles don't track it. Instead they repeatedly move to where the unit last was, stop, then start moving again.
• When told to groundfire, beetles don't move to the groundfire location, instead they explode the moment they reach the edge of shown AoE radius. That makes groundfire almost unusable.
