Alright, so apparently everybody is out here running at like slower speeds than normal walking. Nobody has posted a fix. Well, I did some digging. Accidentally stumbled on something. It fixes it immediately.

So here's what you do.

Step 1: Install and enable swep (seriously.)
Step 2: Launch a single player game or server where you are the admin.
Step 3: Open up the spawn menu.
Step 4: Locate the right side of the spawn menu and click the "Quick Filter" just for convenience's sake so that you don't have to hold Q.
Step 5: Locate the Utilities tab on the right side of the spawn menu. Click it.
Step 6: Locate the blue tab "The Flash SWEP Reborn"
Step 7: Click the "Speedster" tab
Step 8: At the top of the new tab located, you will see "speed." Use the slider to select your U/S speed. I put it all the way up for my own fun. Also, every other option there lets you further customize your speedster experience.

That's it! No resetting or anything, it just fixes itself from there. Have fun everybody and happy Easter!
