No, the problem isn't really the missing 2 hours needed to unlock everything ... again.
I have 4000+ hours and went through a lot of bugs, Railjack was the worst, I almost quit and lost some player buddies there. But the problem here is not really a bug.
They made wrong choices :
Making such an impactful hotfix on a friday.
Give explanations that are garbage.
Choosing to block something that most players have access at one point ... and that is the worst decision here. They own the databases, they can choose exactly what we have access to. Establish rules based on MR or StarChart progression or whatever, just to limit the number of players affected by their own problem (bug or poor software design ?).
And we, players, have to pay the price, in hours, not of a bug but of a decision.
