I just started playing again after a year, hoping that all mods are finally gonna be stable since 1.12.2 is final release.
I found that this mod was finally actually updated and working (Woot!) but, unfortunately, there is something seriously wrong with it. I lose so many kerbals for no reason at all... they just disappear. I read through the comments here and saw that this issue was reported before and supposed to have been fixed... but, tonight, i just lost 4 out of 7 kerbals. i lost the first 3 just going EVA from one ship to another... everything seemed fine, then when i brought the last one over, the ship was empty...
The last one i lost after arriving at the mun. she eva'd to get the science and upon entering the pod she ceased to exist (her science was still available though). and i was left only 2 poor kerbals that survived out of the seven that applied to the mission. Often times, kerbals just randomly disappear , i.e., you have 10 kerbals someplace, you go away and you come back and there are only 9... anyhow, after a week of hoping this will get better just started a new save without this mod and will see how it goes.
Not related to the above bug, but you need to give a control for kerbal death (besides maximum average life)... like damn... i move 10 civilians to a new place and 2 of them die within like a week at 17 years old... if someone passes astronaut school they should be smart enough to not just randomly die a couple days after arriving at their destination...
