I just lost hours of my work on another project, so I guess a big
warning is in order.
Transifex has a new "feature" that if you correct some strings offline
and then upload, Transifex will silently ignore your changes. At least
with translator permissions, I haven't checked yet if this also happened
with reviewer permissions.
Already reviewed strings are now completely impossible to correct
offline - at least the upload window will inform our about that one.
I already contacted Transifex about the issue.
