It is indeed disconcerting.
This bug is not the subtle kind, it is the kind that stares at you. Not having a character available, and not having the most recent updates would be noticed even with junior level project management.
In my not so humble opinion, the combination of the project managers, developers, release engineers, and testers, are all to be held accountable for this.
Either they continue to support the Linux port, with the value it deserves, or they drop it completely.
This is not the first time that this happened. This is a deal breaker and a showstopper.
