Omgggg... Sorry that happened... I have fixed it now - even if you get clipped through somehow, you won't fall down too much, and I do thank you big time for mentioning these bugs!!
I hate to keep throwing these bugs at you, but this one's a little bit of a doozy (and possibly partially my fault?). On version 1.097, the initial Agressa appearance (under the river) overlaps with a kill box! It's still possible to get her dialogue by spamming E while you fall, but you can't run around down there without getting sent back to the nearest platform.
