I had the same bug but i did a clean reinstall of the complete package BGT, etc. and BP1.75 with patch and its still there.

How did gnolls that lying dead pass that point then? Try to redo that battle...

the three elite gnolls on the right side off that 'corpse pile' didnt get past they walked up and down the staircase in the pit until imoen shot them all down

ops that was me - forgot login in

hm i portet my party to the other side (with ctrl+j) rescued dynaheir and cleared the gnoll keep area. And now my characters can walk past this section dont know what changed it. I loaded a safe from before, that i made as i first ran into the problem and there the problem still exists.

EDIT:
i have put your file in the override folder but the safe before i portet myself to the other side has still that problem

I know that its not a problem in an unmodded german version of BG1 i was there more than once and it was never a problem

It seems that you character is just overloaded with numerous halberds you've picked up. Don't be so greedy and try to drop some stuff....

no he is not overloaded

he can still walk (e.g to the left where the other characters are standing) but not past that point to the right
