I committed my changes to local master, I merged my changes with the works of another developer who was also working on master, she made few commit before my commit. Finally I made a merge of my work to hers, now it happens that my commit overwrote her changes in the repository. It is there anyway I can revert back the merge?
o - bad merge here that I want to get rid off
