First off I want to say that while the mod isn't progressing extremely fast right now I have not gone anywhere.
Last year I went through a small hiatus over the late spring, early summer portions of the year because of a family loss.
This year I am likely a lot less active over this time period as well, but at least everything is good on my end!
I have started filling in gear stats for the tier1 sets, and finalize the last pre-elemental crypt fights. I am going to slowly work to releasing the first tier1 sections over the next couple of weeks. This of course is NOT my main priority right now. I have a few younger kids (4) and summer is a family time. Going on hikes, camping, and such.
With my lower amount of activity the other devs are also less active, as I am the driving force here, which is how I built the mod. I will go through quick spurts of tweaks and fixes and such, and expansion when I find the time to put into the process, but I do not hold the others to any schedule. Their work will find a place when they want it to as well.
So I am just stating for the record, the Mod will continue. Tier1 will be released (Most definitely over the summer). But it won't be at a hectic pace again until the end of summer when I can put more time into it like I did last year near the end of august to march.
