Print fails - Peopoly Phenom L - Siraya Fast Gray

Hello, i have problems with my print, maybe someone can help me. Its my 5th day of printing so maybe be these fails are obvious, but it would be nice if i could find help here.

this starts right after the floor is printed and it starts to print the walls. I have printed this part 3 times already and it always happens on the same spot.

and the second problem is that the radius on the outside isnt like its shown in the modell it got a big step in it, this step starts where the hole from the pictures above happens.

maybe somebody got ideas to solve this, thank you!

kind regards,

Are you printing the part at a 44.44 degree angle?
Which slicing program are you using?
Are you assigning your own supports or auto supports?
