There has been more and more aim botters, fishing bots, etc popping up lately. Did a quick google search and found plenty of sites selling these hacks. The most troubling is the XP multiplier and resource multiplier.
This is directly from the hacks website and even shows a video of them using it:
ESP including x-ray loop drops, find important resources, scope out different animals, and always be alerted for explosives
Aimbot with selectable miss rate - Bullet gravity and speed change - Arrow gravity and speed change - Make the arrows and bullets fly straight and fast.
Fishing bot
Unlimited Resources and XP multiplier
This needs to be sorted ASAP otherwise the game will die with flooded resources. It also explains why some people I fight with the bow never miss a headshot.
