Mysterious XP gain

Question

What could give a 100XP boost (not a best answer or badge)?

Answer 1

If you were doing challenges, high chances are that you triggered implicit badges which are still tied to certain languages. E.g. Complete n times challenges using one weapon badges. They are actually available for all languages, and can trigger once for each language.

If I'm not mistaken, the source of this info is @Krishna.

Answer 2

For some reason my XP is also mysteriously increasing and decreasing spontaneously by 30+ points. Is someone messing with me? XP built upon user-controlled threads are tough. 😐

Answer 3

Ahh ok! So I got it from a 50th win in Java then.

Answer 4

@Helioform : You are right. That's where you got that XP from.

Answer 5

can anyone confirm really small XP gain from posts likes?

i keep getting small amounts here and there (can see notifications of likes, but nothing regarding XP rewards)

[edit]
found the reason on another post xD
additional 1XP per like IF best answer
