It's a second child 5 months (well, now 4 and half) to come. Per se wouldn't be such a shock since he and his, i presume, wife have been there already. So i guess the situation got some complication.
The guy came here and on patreon, explained he won't be able to work on the progect in the next months, stopped the patreon payments, what else was him supposted to do? I think he behaved professionally.
So let's allow him his deserved privacy. If in april this game will be abandone, bummer, it was a great project. If it starts again i'll be happy to play more.
