Why did C3 delete my addons?

Why did the new C3 update uninstall all the addons that I had previously installed? Now because of that there are some games that I cannot edit because C3 asks me for those plugins and behaviors that were uninstalled in the new update. That has made me waste a lot of time. Please don't do that again.

That doesn't usually happen, did you manually clear the browser cache? Or using a different browser ?

so that was it! They should fix that so it doesn't happen to us again. There should be something that saves those addons so I don't have to search for them one by one again.Thanks I appreciate it. Next time I'll try to remember that.

C3 plug-ins are stored in the browser cache. If you clear the browser cache, the data will not exist.

But you can check Bundle addons in the project properties, it can help you store the third-party add-ons used in the project along with the project file.
