Bug description

The code is taking ReqPoints as the "cost" for the passive skill, rather than the normal 1 point and checking if ReqPoints has been met by learned skills in the same skill tree.

Steps to reproduce

Have 1 unused skill point, and try to learn a passive skill in the same tree (or others for that matter)

Expected behavior

Learn the passive skill if at least 1 skill point remains
