Lost changes after merge

Hello,

  I have a very strange issue described below:

* Here is the tree before I merge via `git log --format="%h %p %d" -n
20 --all --graph`:

* Here is the output of `git log --format="%h %p %d" -2 path/to/file`:

a008c4d580 c61f96eb5d a274b6e7ca 67c1000ca3

* Here is the merge commands:

git merge f087081868 # fix conflicts

* Here is the tree after I merged via `git log --format="%h %p %d" -n
20 --all --graph`:
