# Animation nodes list remove bug?

Maybe this is meant not to work but when I try to remove an element from a polygon indices list, the an shows me an error. Same thing if I try to loop to fake a list copy

Here for example I want to remove the 4th and seventh faces from the polygon index lists, and it shows me the red border.

Can someone explain why this is happening? I don't see any clear reason. Also the remove list element node works perfectly for edge indices and vertices locations

I am using a cython version of an, maybe this is the problem

• I think this is part of the Cython implementation and polygon index list is missing some item accessors (maybe) and that should be reported github.com/JacquesLucke/animation_nodes/…. – lemon Apr 17 '17 at 20:28

• the error show in the console: Subscript deletion not supported by animation_nodes.data_structures.lists.polygon_indices_list.PolygonIndicesList – Pascal Nardi Apr 19 '17 at 16:56
