I need a help. I'm trying to export an object and experimenting the folling error at the "erase coplanar edges":
An error occurred in Round Push Pull
Error in generation of the geometry

reference to deleted Entity

jointpushpullgeometry.rbe: 1023 -- entityID
jointpushpullgeometry.rbe: 1023 -- block in geometry_coplanar_edges
jointpushpullgeometry.rbe: 1020 -- each
jointpushpullgeometry.rbe: 1020 -- geometry_coplanar_edges
jointpushpullgeometry.rbe: 366 -- block in geometry_robot_erase_coplanar_edges
jointpushpullgeometry.rbe: 362 -- each
jointpushpullgeometry.rbe: 362 -- geometry_robot_erase_coplanar_edges
jointpushpullgeometry.rbe: 220 -- robot_call_action
jointpushpullgeometry.rbe: 183 -- geometry_robot_exec
jointpushpullgeometry.rbe: 166 -- geometry_robot
jointpushpullgeometry.rbe: 81 -- block in geometry_execute
lib6operation.rbe: 370 -- step_geometry
lib6operation.rbe: 305 -- block in yield?

What i'm doing wrong?
