Hunting in the savanna seems like quite an adventure in this game.
The bugs you encountered, with animals becoming invisible and ducks not behaving as expected, can be a bit frustrating, especially when they disrupt the flow of the gameplay. Technical issues, like GPU temperatures, can also be a concern, but it's good that you found a workaround with undervolting.
It is, it is quite dangerous at night, but also during the day, as lions lurk. Nobody likes to have their game interrupted, so those bugs did bother me a bit, but the worst was the issue with my GPU, if it happens frequently I will have to change the thermal pads and improve its cooling.
I hope it won't happen frequently but if it happens, you'll have newer and cooler things 😎
