Hello.

If this wasn't brought to your attention I'd like to do so formally on here.

The Creative Commons BY-SA 4.0 license is only one-way compatible with GPLv3. This means that a Creative Commons BY-SA 4.0 work may be distributed under the terms of GPLv3, however a GPLv3 work cannot be released under the terms of Creative Commons BY-SA 4.0.

By this project existing as a SourceMod plugin, you have no choice but to release your work under the terms of the GNU GPL v3.

I suggest this be changed as soon as possible, thanks.
