Here are some example of perplexing behavior fixes:
- https://github.com/Unvanquished/Unvanquished/pull/1248, that fixes some tiny things like when the UI showed 6.0 morph point, except you actually have 5.96, and can't evolve because of that
- https://github.com/Unvanquished/Unvanquished/pull/1251, that adds some visualisation to make a hidden healing feature more explicit
- https://github.com/Unvanquished/Unvanquished/pull/1281, that fixes a "corpse teleportation" glitch
- https://github.com/Unvanquished/Unvanquished/pull/1287, that fixes a "reactor zapped through walls" bug
- https://github.com/Unvanquished/Unvanquished/pull/1550: a stepping stone towards a tutorial: if you want players to learn how to destroy the enemy base, you need bots not to destroy it before they do.
- https://github.com/Unvanquished/Unvanquished/pull/1546: it fixes quite some oddities with the armory, that can be confusing for people
- https://github.com/Unvanquished/Unvanquished/pull/1484: it is always frustrating to be denied evolving just because you are too close to walls
By the way, for the "aim at head" thing, we can also consider a tutorial where enemies are humans in battlesuit, except they forgot their helmet :P We could also add some feedback in-game, for example some sound when headshoting.
