issue when using the "polygon skeleton as line barrier" option

[YG1975]

Current Behavior

When creating the landcovermerge for Senegal, I had to give up the use of the "polygon skeleton as line barrier" option, as even after leaving AccessMod run all night, it did not work. I am not sure if it is linked to the particularity of Senegal. I used AccessMod 5.8.2-alpha.3 on Mac with Mac M1 Pro chip.

Expected Behavior

the use of skeleton option should be smooth
