Hello ive been trying to rotate and flip my gcode paths via the visualiser and it keeps either raising the error "Index 0 is out of range 0" or raising a "gcodeMeta.point is null" error

Im using the latest version of UGS at the time of writing (Version 2.1.13)
On a windows 11 laptop.
I used autodesk fusion with this (https://github.com/Strooom/GRBL-Post-Processor/tree/master) post processer (I wasnt able to use the inbuilt grbl PP at the time)

the error log for the second error is as follows
java.lang.NullPointerException: Cannot invoke "com.willwinder.universalgcodesender.types.PointSegment.point()" because "gcodeMeta.point" is null
