if you freeze while fast forwarding it is not a bug in the game it is a bug in the engine. rpgmaker cannot accept fast forwarding at all, it’s a flaw in the engine, and one that is hilariously easy to fix:
all credit to this guy who posted the solution:
First go into the games “www” folder and from there open the “js” folder. Once there open the file “rpg_core” in Notepad or some other text editor. Once open, you need to find the line:if (this._skipCount === 0)
You can use ctrl+f to quickly find it. Once you have found it you need to replace it with this line:
if (this._skipCount < 0)
I found this fixes the visuals freezing. Make sure to save your changes before exiting. Also you will need to do this again once the new update comes out.
I’ve used this in virtually every game i’ve played in the past year to great success.
