Greetings! I have yet to encounter any bugs in the EE up until now, but now I find myself stumped. I am playing a sorcerer character and I am in Chapter 5 of SOA (BG2 EE). I did a completionist playthrough, so I got to above 3 million XP around the end of Chapter 4. In the original, this would be above the level cap, but in the EE they removed it for SOA and set it to the same as TOB. Thus, I took time stop as a 9th lvl spell, and improved alacrity as an HLA (which was added to my spellbook).
I just finished killing the mind flayers in the eastern tunnels. When I returned to Ust Natha, I found that improved alacrity had disappeared both from my spells to cast as well as my spellbook. I have determined this to be a result of the temporary INT drain my sorcerer suffered from a mind flayer hit or two, which created a permanent loss of Improved Alacrity by reducing the max number of spells known. This, to me, seems like a bug. Or failing that, a really frustrating and unfair game mechanic that punishes sorcerers.
I was puzzled but determined to fix the problem using EE Keeper. However, I can't find Improved Alacrity in EE Keeper in order to add it (I went through the whole list and used the search function - it's not there).
When that didn't work, I resolved to use EE Keeper to add enough xp to level up, select Improved Alacrity, then manually remove all the other changes in EE Keeper in order to return my level to what it was (Lvl 18). However, this didn't work. When I leveled up, the level-up screen displayed Improved Alacrity as having already been chosen, and could not be selected again. But of course, it was still unavailable to cast and missing from the spellbook.
I am tremendously frustrated by this. As a Sorcerer I can't fix it just by buying a scroll. I'm stuck. I don't wanna go through the game without one of my hard-earned HLAs, so I'm stuck loading my last save all the way back at the beginning of Chapter 5. I'm just posting in the hopes that someone has a fix that is less tedious. For now I'm going to switch to another game because its just too much of a hassle.
