Hi @Kafka - Honestly, this is a really cool thing that the developers would fix a bug so quickly and compensate players for the in-game currency they spent. Having said that… Any chance I can be compensated for the broken Steam Exclusive Items for which I paid real-world money? 
The preferred compensation would be to fix the items so they work the way they are advertised and give the set-bonus they are supposed to give. If the developers won’t do that, then I would kindly request other means of compensation. I reported the bug over half a year ago, and still this hasn’t been fixed.
