I made sure to follow the correct install procedure and applied no other mods or just the bg2fixpack core, yet always get the same results. This would make me think these things happen to everyone, though I found no mention of them..
- Upon joining the party, a BG1 character who has the same portrait as you has his/her portrait correctly swapped to alternate on the main screen, but displays the small version of 'man in plate armor' in the character screen. (regardless of sex)
- The 'Default' BG1 voice-sets, both male and female, don't appear among the choices when creating a character.
- Looking at Phlydia, apparently some voices got changed. She had a sort of gimpish or child-like voice in BG, but has a 'sweet' one now.
- Sometimes the random spawns contain creature types that should never be found together and it looks out of place. (this is a regression from the original game)
Some more striking examples would be: bandit and a gibberling ... skeletons with 2 species of bears, one hostile and one non-hostile .. skeleton, gibberling and hobgoblin ... cave bear, gnoll ... ghoul, ghast, bandit.
I know it can be fixed by using a different spawn system, but this is what everyone uses by default.
