While I was carrying the bound enemy, I was attacked by the new enemy. After the battle I couldn't drop the enemy or hit ESC and X to save the game, and after that the protagonist couldn't be tied, but I could hit SHIFT run. the draw was normal.
I had encountered a similar bug in the Stromm Marshes where Seles was carrying someone but couldn't drop the enemy. I could fix this by ambushing a female enemy to grab and release which resets Seles' graphics.
