[OLD! See at the end for solution!] I've the same problem when my Kerbals are on Mun... I can't even use the jetpack! They're attached on the floor and won't jump / fly! I've some mods installed in common with you: Asteroid Day Kerbal Attachment System Kerbal Inventory System Mechjeb2 SCANSat Station Science Maybe one of these has this bug! I've also noticed, opening the debug menu (ALT-F12), that pressing space for jumping on Mun, on the Debug tab is written: [CurrencyConverter for Unpaid Research Program]: 0 Reputation taken, yields 0 Science EVERY TIME!!! So now I've a log full of these...... What's happening? ________________________________________ EDIT!!! After some work, PROBLEM SOLVED!!!! It's not a bug... it's a feature xD For me, my Kerbal has its inventory full at 250/300 of its capacity... Lowering it's inventory made its jump more and more high.... Emptying the inventory restored the normal jump to kerbal! Feature of KIS, for me it worked! Try it yourself and let's see if you have same problem! Alexej
