Note that this happens with many operations (bisect for example) and isn't spesific to bevel.

This is caused by the undo system not taking local collection into account.

This seems to be only happening on Blender 2.82 (it does not happen on 2.81)

Hmm, well my file was failing for 2.81, so either it’s a separate issue after all, or something else about 2.81 is obfuscating the issue for only the other file.

Tautvydas Andrikys (esminis) added a comment.Jan 27 2020, 10:02 PM

Well I am using old 2.81 Alpha build (Hash: 7790298f6191, Date: 2019-10-09 11:41) so probably something changed since then
