Hey we’ve just pushed out a new version of tk-multi-workfiles2 which is v0.12.3, and that allows you to save versions up to 9999999 which hopefully should be enough.
If you are running a centralized config you can run tank updates from the command line, or if you are using a distributed config, you can just update the required version in source config’s environment files or use the update action as detailed on step 2 here.
