I'm happy to look for a sub for Nief if it helps. The empire looked in good shape until Jazzepi's aggressive multiple mouse slips
If I start the search now then we'll have a good 12 hours before hosting for a sub to come forward, and if Frozen Lama can do a turn or two then we'll have a day or two to find one.
I personally really hate seeing nations go AI due to the huge unbalancing it causes, and here it seems silly to me to turn a powerful nation like Nief AI just like that, since their position is probably fine. Plus some of us are having to fight tooth and nail for every single province, so wouldn't want to see others getting freebies
Edit: Have done a sub request post, and will contact Frozen Lama and ask him if he would kindly do a turn or two if a sub doesn't quickly appear.
