Transifex created pl.po.orig file in po directory by accident. Please remove it.
Removed. Have you opened or would you open a bug with Transifex? I can't think of a reason why it should create files that previously haven't been there (or don't match the pattern for files it is allowed to touch).
Thanks. I would do it, but I can't reproduce this behavior. If it happens again, I'll do it.
