Strange to me too and I've had all day to think about a root cause. I know of only one thing I might have done to inadvertently delete the folders. Yet the conundrum of even that possibility is every single .git folder should have been deleted throughout the entire tree. That is not the case. Further, stand-alone files such as .gitmodules would have been deleted too, but those files are intact. Other than the .git folder the remainder of the tde-i18n module tree is intact. Yes. I also tried git clean -f. Running 'git pull' results in an 'Already up to date' message and no errors. When I run the switch_all_submodules_to_head_and_clean script then the proverbial hell breaks loose because some of the modules are missing the respective .git folders. At this point I just want my local tree updated far more than solving the mystery of what happened. Further frustrating is the Trinity git server is really slow with respect to cloning. According to the progress bar, I'm downloading at about 80-90 KiB/s. At 1.1 GB and a 3 Mbps connection, the tde- i18n module should finish loading in about 50 minutes. I'm still waiting 90 minutes later and the tde-i18n clone is only 64% complete. At this rate, cloning the entire tree might take days. :-( Darrell
