On Cyberduck Build 33705, uploaded a folder (~1GB, ~1000 files) into vault successfully with checksum done. Vault should be the newer format as it was created on 18 June 2020. Upon re-login, received error.
"File not found. /My Drive/redacted/d/F6/RMIHYNOVUKPK7LMQ25HEEPC5QUGQU5. Please contact your web hosting service provider for assistance."
Have not been able to access files in the folder, on both Cyberduck and Mountain Duck, since uploading it 2 days ago. Longest no. of characters for filename was 110. Have updated to CD Build 33082 and MD Build 16777. Problem still exists.
I've tried to replicate the problem and was able to. The folder on the deepest level had showed that it isn't properly synced, though the files in the folder appears to be successfully synced. Part of the Mountain Duck log is attached.
