Bug (?): Acquisition during research

[Tomgs]

Yes it happens that way when you are researching a field and it is given to you either through finding it on a special world or by intell operations or another race gives it to you. The research points that you have already put into that field will just apply to the next higher level of the field if there is one. Its a nice touch so that you don't lose the points that you have already spent on it.
