Weird Higgs sector in linear seesaw model

Hi, I tried to use the linear seesaw model coming with the SARAH distribution with SPheno. Otherwise everything works fine, but the Higgs sector (+ W-boson mass) comes out incorrectly, the lightest Higgs is (no matter what parameter choices you pick) between 87-92 GeV. I noticed that for some reason...

Strange behaviour with low scale type II seesaw

I was trying to use the type II seesaw model (generated with SARAH) in SPheno at with low scale input and got consistently error messages. With some testing I was able to locate that the problem is that the down-type quark and leptonic Yukawa couplings blow up at some point. They are OK for the firs...
