I am new in git and have problem in merging.
Scenario :
I have a master branch. I create new branch dev from master start commits in dev branch . After two days I create new branch devmerge from dev branch . Now one team was start working on devmerge and one was on dev. Now dev is also some commit history and devmerge is also some commit history but the problem is when I want to merge both devmerge to dev the result missed the some commit history of dev (some dev data is missed) . I don't know what is happening .
