Some unintended mechanics that should be fixed (video)

[Geovane2299]

I've made a video talking about some unintended mechanics (or maybe some are just easter eggs, intentional broken stuff) that I do think that could be fixed. From those, the ones I think should be changed are:
-Losing a mode item (like the Ztar, as showed on the video) by falling on lava causing it to reappear repeatedly, causing SFX issues.
-Insta-killing Bosses with the Star Powerup.
-When setting a player's control to mouse, it won't actually appear on the menu, even though it still works.
-In CTF, when 2 flag bases pass in front of each other and you start getting points really fast by holding Turbo button.

4th could be prevented by disallowing flag bases to spawn overlapping (or in a certain proximity of) other flag bases
