Loot distribution seems to be bugged - you might want to hunt solo until it's either fixed or confirmed that it works as designed.
I tested last night and it seems fixed. While it was bugged I could not get a loot over 1ped from Rudolf Dragon Youngs, then after leaving team I was getting the 2-5ped standard loot again. Last night I tested in team, and was able to get the 2-5ped standard ok, so we teamed up and went after BIG THINGs.... and ended up with a 8k ped hof :)
We hunted some zombies in a team yesterday and didn't notice anything extraordinary (because loot on them is usually cr*p apart from few bright moments :P). I believe loot tends to be generally 'on condition' after server reset (also on rarely hunted mobs/spawns) and 'warms up' towards 'quantity' thereafter; maybe all this was about sample sizes and coincidences being noticed. edit: we hunted fight after the minipatch though; but loot distribution is certainly serverside anyway.
Ok, this issue seems to be solved so I'm taking it out of the slider rotation. Just found this in the Client Loader: And I want to point out that this is the way to go, the one and only in case of issues potentially wasting PED and/or time and/or being at least moderately annoying. Considering how easy such a warning can be placed I find it even more disgusting that it didn't happen in the case of bugged team loot and many other cases. Also absolutely disgusting that in case issues are mentioned by officials they are hidden in some thread on some 3rd party forum instead of being displayed in the Client Loader. Many thanks to ROCKtropia for doing the only right thing and by doing so establishing the standard for future potential issues.
