Imugi disappear after detaching

Hi, I wanted to ask if it is correct for Imugi to disappear when the part it is attached to is destroyed. This is the same mechanic as Phoenix and Fukibari, however those weapons received hit damage and penetration to get through pass-through parts. and player skill is to hit cabins and weapons. For the Imugi… a well aimed volley can do lots of damage or nothing depending on what the nades stick to.

Any part will be destroyed if the part it is attached to is destroyed.
This is why it’s best to mount weapons on either your cabin, your frames, or pass-through parts (gun mounts, buggy floors, etc).
Pass-through parts generally have low HP, but since most damage passes through them, they are very durable. Check the icons to see what parts pass damage through, or have other resistances. They are sorted to be in the first section of your storage.

Edit: just realized you are talking about the little sticky bombs, and not the gun itself. Sorry!
Makes sense that the bomblets fall off of the part they are attached to is destroyed.
