beware o' sea monsters and broken codes

So my fawn Nerezza (pictogram WhiteThorns) doesn't show on the map half of the time she's on. So far, since I've started counting, she's been on the map 11 times and off of it 13. Maybe it's my connection, I tend to have issues connecting, but anyone know why this would happen?

Hi! I'm new to The Endless Forest. I'd heard of it before but I finally dove in.

I'm having trouble with a technical issue. I can't alt-tab between the Endless Forest and another windows because it crashes. I searched on here and saw an answer about ticking the setting to run it in a window. I did this on the separate settings and in the game. I got a notice saying my settings would be saved and telling me to restart the game, so I did. The box was unchecked! I tried this with other settings and it's the same thing. How do I get it to stick?

Earlier I was wandering around and met a deer. I greeted them and there were these green circular symbols around. What does that mean?

Sorry if these are really basic questions and I hope I'm doing this right! Thank you!
