Fairly sure it has to do with how voice lines are stored in memory. It is very resource intensive to store and que them since every second the RAM asks- is it done? Is it done? Is it done? Ok play this. 8 lines of speech that are most likely done by sound vVA need to be rendered and processed into the right format and then processed in real time to the right speakers.
This is why Larian have set it to 4 companions and not 8 like the mod. Maybe with enough hardware it would be possible. That or maybe your mod bricked something. I don’t run any mods and my companions say more then one line.
The above interruption problem can be seen with monologuing by NPCs. If you steal or attract them, they stop and never continue speaking. This is something larian needs to fix or change
Am I in the BG1 forum? It can be an issue if you have 4 MB ram.
