Overwriting of asset fails with Github release

I’m trying to update an existing Github release with new assets but getting the following error:

Yes, I have the same issue. Trying with both dpl v2 and v1. I’ll keep experimenting and see what the cause is.

In dpl v1 it does work. Have a look at https://github.com/Return-To-The-Roots/libsiedler2/blob/56ac0cfab9be2e1558fd24ba3bf9f5c71b21f4ca/.travis.yml where we do releases for windows+linux

I wanted to switch to dpl v2 but that didn’t work
