Today I have found, more or less accidentally, a problem that seems to stem from renaming Scholarship to Academics:
When the dialog engine checks for the computer skill in order to decide if you can still learn from Bertram, after returning his CD, it seems to check for the first entry in the knowledges part of the character sheet. So if your academics is already at 5, you can't learn anymore, even if your actual computer ability is only 2.
Until a hotfix can be made, please keep that in mind. The easiest thing is to keep academics at 4 until you get past this point.
If you need academics 5 for some reason before you get to this point in the game, you can use the console to sidestep the problem. Use "vstats get computer" I hope I have the syntax right, but when you start typing, the command should turn up anyway, so you can select with the up and down arrows once you have typed vstat get c
Sorry can't do anything more about it right now
Tuesday is Soylent Green day.
