Upon deletion, characters are wiped from the server. So if you delete characters before the points are allocated, you'll miss out since the system has no way of telling it ever existed.
Well, I accept this (anyway I dont have another choice). BUT, it's not my fault, it's GGG fault because knowing this kind of issue they sould:
1º They should block the option of removing racing chars if they are to be granted with points until it's done. Tt's known the problem allocating the points and it's normal that players remove their chars once they have seen they're in VOID/HC League (that's my case).
2º They should flag the character with the challengues finished (it's just one record or several columns more in the Database). So that, even if they character get removed, they still have that information ready to be consulted just in case.
