I've encountered the same problem when i try to split some polygons. I don't really understand what was the problem, just some hint:
- it occours only on windows. The same shapefile works fine on Linux. - it also affects qgis 2.14 - is not connected with topology error. The problem remain also after using v.clean. I hope this could be useful Luca Il 16/Set/2016 03:08, "Nyall Dawson" <nyall.daw...@gmail.com> ha scritto: > Unfortunately a fairly nasty regression has slipped in to 2.16 and is > still present on master.
