Just did some testing and this bug happens when you have two copies of the Simple Variable Updater script in your game.
This shouldn't normally happen so
DO NOT:
-add scripts in the Gaijinizer/Plugins folder (you should always have the same plugins scripts as the latest patch)
-attempt to patch game after replacing the Data folder with Gaijinizer/Game_en/Data. (Or patching a game translated by RPGMakerTrans.)
That should also explain why the fix behaves differently from user to user.
I'm going to add some kind of specific error so this won't happen again or at least the users will know what they messed up to a certain extend.
Deleting the Gaijinizer folder before replacing it with the newest one is always a good idea, so do it as that may fix the bug. Also be sure the Data folder is actually from the vanilla game.
Edit: I'm putting the new script here. It can safely be used to replace Gaijinizer/Plugins/3_Simple Variable Updater_SHRIFT. It's not completely foolproof but it should warn most user if they messed up. Next patch will include the updated script.
I can technically get rid of the message but I can't be sure when someone uses an obsolete version of Simple Variable Updater that doesn't disable itself. Getting rid of it isn't difficult either, just don't mess up.

So yeah, if from the next patch on, you see this, then you might be interested in actually reading this post from the beginning--not just looking at the picture. (don't mind it if you're one of those that read the posts)
