Actors can't walk when i edit tiles color

Hi! So I'm new to RPG Maker, and the over saturation of the map tiles really bothered me, so I wanted to tone the saturation down a bit.
All I did with the tiles was change their saturation brightness and hue, I didn't move them or anything. And after importing the tiles into the database and stuff, when I go onto the map my actors can't move :(
The only thing that seems to fix it is to restore put the original tiles back.

Is there any way I can keep the tiles the same color and have my actors walk?

Can your actor turn at all? Can you open the menu? If so, you need to check your passability settings on the imported tileset.

If you cannot move at all or get the menu to open, it suggests that it likely is an autorun event going that you've forgotten about.

Oh thank so much! I deleted an auto-run event and it works now. I'm just curious as to why it would cause that to happen though?

Autorun events remove control from the player so they can't move or access the menu while the event is in progress. Think of them as cutscenes - you want to stop the player so they can watch your scene, and then they can do stuff again.

If you want to do stuff in the background but still let the player do stuff, use a parallel process event instead.

Note - both of them loop by default, and if you have too many parallel process events running at once (or even one that's not designed well), you can cause a fair amount of lag. So it would pay for you to spend some time learning about them (and the other event triggers) so you know when is the right time to use each one.
