I don't know if its a bug or just my computer but there are areas in each of the new areas in version 3 that when I'm moving with a mouse will only move 1 to 3 steps and then stop when it should move much further. One of them is the tent u walk under to get to one of the fruits.

We're aware of this. Unfortunately it's an issue with RPG Maker itself, not something we can do anything about. In simple terms, mouse-click movement will halt whenever you land on an event tile. And because we have event tiles to play noises or make the tent transparent, it stops you.
Sorry but there's not anything we can really do about this. That's why we recommend using the arrow keys as much as possible.
