I'm on Assets 2.2.2. Today it told me to update so I clicked the update button. This happened:
A Database Error Occurred
Error Number: 1146
Table 'db509793644.exp_assets' doesn't exist
UPDATE exp_assets SET file_path = REPLACE(file_path, "}/", "}")
Filename: third_party/assets/upd.assets.php
Line Number: 298
Now in Add-ons -> Modules I get @@@VERSION@@ as the version. No clue on this one...
