Tonight, I've learned something.
That I should not only make several saves of my main project, but also make various saves of the plugins I use or have used. But for now, I may be unable to keep working on something I was bulding for months, so I'll think about this fancy lesson latter.
Today, I've decided to reset my PC. Great idea, now everything is waaay smoother and my OS is waaay more clean. All the important files previously saved have been brought back, including my main Construct 2 project. But hey, I can't open it because several addons are missing. I've managed to download them all, except one : The Clock plugin, by Yarfapet.
This little prick is simply nowhere to be found. I didn't even know I've been using this, it must be from one of the earliest iterations of the project, and I've never removed the addon, even if I was not needing it anymore. And right now, I truly hate myself for this. This is the original thread, if anyone is interested :
Google failed to help me, this addon seems to have vanished from the entire internet. I do hope that some of you have still this thing saved on your disk, otherwise I'll need a serious quantity of alcohol to deal with such a stupid situation. Any form of help would be appreciated. Thank you
