I was in the game for a hot minute today from a computer I haven't used before to play. Usually I am a MacBook on Safari or Chrome, but today was on a Windows Dell Laptop using FF.
I was in Groddle Junction, took subway and then teleported back home to 3213 Estevan Meadows Quarter. All was normal. Once I walked into the house, I kept walking, and I couldn't stop. I could change directions with the left/right arrows, but could not stop moving. Tried to tend to my trees and couldn't click on them due to losing focus by walking away. When I walked by a tree, I could hit enter and then water, etc. After the task, I would start moving again and couldn't stop. I tended 3 trees, and still the squirrely behavior.
I tended to 3 trees and then walked straight into the door. I had to leave the game so that's where it stood.
I have occassionally experienced related navigation issues before, but usually *NOT* being able to move using the arrows and having to use the trackpad and click to move forward. If I reloaded the game, it would go away. I did not try to reload this afternoon because I didn't have time.
