FIXING THE BUG WITH THE LEVEL UP
PROBLEM:
Sometimes, when you overcome the amount of experience required to level up, while we are in a Boss Epic, our level is not updated: Neither get skill points nor your energy or stamina refilled.
SOLUTION:
Simply go to missions and perform any one to upgrade your level and get both the 6 skill points as your energy & stamina refilled.
NOTE: Try to use this mission to give you the maximum points possible experience, according to the energy available to make the best of it.
If you have no energy when this bug happen, just wait to regenerate 1 point and make the first of the missions available for upgrading your level.
