Does your project take forever to startup?
Repetitive dependency installation may be the reason.
Automatic1111's base project sets strict requirements on outdated dependencies.
If an extension is using a newer version, the dependency is uninstalled and reinstalled twice every startup.

Unable to use extension since it does not care I've got 0.0.17 automatically given by A1111. But you are forcing me to use outdated 0.0.16

Was installing and trying different versions of xf, they are working great with SD but Dreambooth got problems with it no matter what.
I solved that by uninstalling your extension and found different one that works flawlessly with more features.. Thanks.
