I wouldn't necessarily say the mod is properly dead... the mod author is still determined to see it through to the end even though he isn't active on this forum.
For fans following the project: Logan did, at one point in the past, cancel the project due to health reasons and only resumed development after several new modding tools were released which made world building much less tedious for him. Even though he's back to developing ROR those health reasons likely haven't gone away, when we consider this (alongside the Covid-19 pandemic and the global recession it caused) there are no doubt valid reasons why the development of ROR has been significantly delayed.
At the end of the day: modding is a hobby and no modder is obliged to the mods that they've made or developed... so if a modder has health problems, employment obligations or other private issues it's common sense that modders focus on any of those reasons rather than their mods.
As a ROR team member, I know ROR's behind the scenes development, but since I'm not Logan I cannot promise anything... though I can say if Logan was 100% certain he wanted to stop developing the mod he would announce it. As an insider, I can say development is still on-going, though fans should treat ROR like Sleheyron... SithSpecter hasn't cancelled Sleheyron though at the same time the Sleheyron thread has seen no activity for well over a year now.
I personally have faith that SithSpecter is still working on Sleheyron albeit in total secrecy so that he may develop at his own comfortable pace. Like with Sleheyron, players shouldn't be tallying the days or checking for ROR/Sleheyron updates all the time, these mods will come when the developers are ready and when they release it'll catch us by complete surprise.
