I finally figured out why we got the Puri material box as a compensation.
After many weeks of contemplating and talking to the customer support I figured out why the compensation we got was deemed as correct.
I assume the production team miscommunicated or lied to the developer in regards what actually happened. We got 2 weeks of materials from the gardening after not having access to housing/gardening.
But what about the puri ops progress? We got 2 weeks of material worth from purification content. I guess you can make out the connection right now.
It's quite obvious that the production team told the developer that we also had no access to purification for 2 weeks, just like housing/gardening and so EVERY player received a compensation for 2 weeks of not being able to access purification.
As everyone knows, this is not what happened, we all had access to purification but only part of the players lost all progress they had prior to the merge.
Those players did still not get any compensation and the production team should tell the developer the truth about what happened so they can figure out a proper compensation.
