Hi everybody, noob here. I registered to report the same problem you seem to call the kerbin SOI bug. I have a rover on the mun, with the cone module and a bunch of lasers. works fine on the launchpad, but as other reported, once switching to another spacecraft and comming back everything was broken. By that i mean, my subsystems forlder is empty (see screenshot). The gui is there no texture glitch, the mod works perfectly on the launchpad, so no install issues. Romafrer, can you confirm this is the same bug and that your fix will... fix that? Thanks for the great work anyway, i'm new to kerbal and have been addicted since i first tried it, partly thanks to the great community. keep up the good work.
