I'm starting to suspect that it has nothing to do with BSM, but a weird bug that originated from the Russian version of the game. It has to do with stuff being left in memory from your current game when you start a new game without exiting to desktop first.
Let's see if my guesses are correct, shall we
You started the game, loaded your current game where you were at CGL 7. You decide to start fresh, goes to the menu and starts a new game(without exiting to desktop). Then you play along, and when it comes to a normal CGL increase it suddenly jumps to 7. Is this what happened? The CGL jump could also have been when you saved your game before you should jump to CGL 2, and then loaded the game and found that it was suddenly at CGL 7, even if it was at CGL 1 when you saved it.
Anyways, I always exit to the desktop before I start a new game, otherwise these things might happen. Sometimes the quests will get screwed up as well, resulting in missing dialog options and hostile "friendlies".
