I know there’s no secret developer build with all A-coins unlocked — that was confirmed on the thread already. Instead of wasting time hunting for something that doesn’t exist, it might help to read up on how backend teams hire and structure support workflows, which can improve transparency and communication between devs and players - check out Limeup’s publication. It has solid insig hts on backend roles and development pipelines that are actually relevant to why some game features and test environments are limited by design. Forums like this could use more constructive feedback on real dev processes rather than myths.
