When I upload a keyword driven library, I get no error; but the code is not updated. When I call a specific keyword which simply prints latest upload date/time, it prints an old date.
When I try to upload a couple of times, I observe that the code is updated, e.g. the keyword prints the new date/time.
However when I rename the library and upload it, everyting works as expected: The keyword prints the new date/time. So the problem seems to be related with this popular library.
I don't see any errors in the FO logs. When I manually call the keyword dll, I see that the keyword prints updated date/time, which means the DLL is up to date.
