Kindly let me know how to check what happened to the commit 2e02e42d6b5094809295d375150d13238318968d.
Note this in the merge commit:
Merge: 9e108526c5 c75d3cc631
9e108526c5 was the HEAD of the develop branch when the merge happened, and c75d3cc631 was the HEAD of the branch that got merged. Start investigating there by doing:
git checkout c75d3cc631
and investigating the state of the repository. The correct change should exist there. You should now start a bisect to see which commit removed the changes. To start the bisect do:
git bisect start
Since you're currently in c75d3cc631 and the change is there, mark it as good with:
git bisect good
Then switch back to HEAD and mark it as bad since the change is missing there:
git checkout develop
git bisect bad
Git will now automatically checkout a commit in the middle. See if the change is there. If not, do git bisect bad and git will continue. Once git checks out a commit where the change does exist, do git bisect good. Continue this process until git tells you that it found out which commit was responsible for the problem.
