HWS trader bug with limits.
I have found its existence really at a good time. When I wanted to buy something really bad.
It consists of the following: if you try to buy more packages than you are allowed as if you purchased 1, then try buying 4, it will fail.
However, the check on the number of packages bought belives it to be the 1+4 packages, leaving you over the daily limit (or I got lied to again in chat about it being daily).
Now to the “totally the reward”. Lvl 25 reward is a trap. And a really bad one. It does not usually give you the skill points you would get by reaching that level. So you are just stuck at level 25 with only 25 skill points. From 2k or 8k you should have. Dont remember well.
I would recommend removing it or moving it to the master tier, where you get 10k points, too. Another solution is adding the points, but the master tier benefit of 10k points becomes like 20k.
