Wtf, what is this? I found it in a lake

I've been playing this game since BETA & I use to casually see people fishing all the time, especially when all we had was hunting/fishing and the side missions to make money from. I miss when people did this because you can see how truly beautiful & immersive this game can be. What happened? I know there is all big boy job and plenty of better ways to make money in the game now but none of them make me feel like how it feels to just relax and go fishing. 🥲

I deliver them alive and sure I do sometimes but not always, is dying the problem?

I was looking for alligators using dead eye when I saw a box glowing underground. Does anyone know what this is or how I can get to it?

Over 8 hours of hunting and not a sighting. Been hunting spots like the railroad crossing above brandywine drop, aurora basin and tall trees area, burrow lagoon, cortona springs, moonstone and ocreadys run. Ive been using the wilderness camp and silently creeping up to use my binos to scope it out. Ive actually seen the legendary moose twice and still no standard moose or doe moose. Any suggestions? They are the last of my rdo compendium and i realy wanna finish it

this is my first time seeing this, forgive me if this was already asked before, but is it like a dev or hacks?

That's not the name I gave my posse
