Hi, With a large work being developed on branch `A` I created a chain with branches `master` and `A`. I then created a branch named `B` and added it to the chain. I added commits to `B`, then merged `B` into `A` I ran `git pull` on master and pruned merged branches. Now I can't update the chain, I can't tear it down. I can't even list chains. All I get is an error stating ``` More that one start branch: ["A", "master"] ``` Any way I can unlock this, apart from nuking the git-chain config? Thanks!
