Been having problems placing ladders underneath sandstone hatches for some reason they can only be placed on top of the hatch. For anyone having the same problem I used a different material (flotsam hatch isle of siptah DLC) and it worked normally. Hopefully this is fixed or noticed by the team.
Thank you for seeing the post very much appreciated. no rush on the fix other hatches work as a good alternative don’t be like Ubisoft and break the entire game over a simple bug.
