fs.write() ignores multiple calls for the same file

[homj]

I'm trying to apply a set of changes to an existing files. These changes are all applied by a single call to fs.write() for each change. However, only the last call will actually be executed after confirming the file overwrite. The preceding calls are being ignored completely.

There was an error in my code: the changes haven't been applied in the correct order.
There is no bug and fs.write() works as intended
