I found some strange behavior with the newly purchased Version 5 (5.0.2).
Slicing this model with Version 4 work multiple time without any problems.
With Version 5 depending on the angel (Z-Rotation) sometimes parts are missing, sometimes there are parts added and also some times there is strange artefacting.
You can see it in the picture I attached.
Top left STL Model.
Top right should look like this.
The rest... very strange.
I found out I have to rotate the object about 6° to get the correct slicing.
I hope you can fix this problem, if needet I can provide further information.
Thanks and have a nice day,
