Issue attaching intakes

[skiparay]

So I've been having a very weird issue attach intakes to my craft lately. Basically whenever I try to surface attach an intake, I get the click that the part has attached, but the corresponding model doesn't appear on the craft. When it comes to attach the intakes via nodes, i get a similar problem, but in addition the nodes on both the intake and the part I was trying to attach to disappear. From my testing, the problem affects intakes and intakes only. In addition, I think the problem may be linked (at least for me) to KSP Interstellar. The problem doesnt seem to appear when I have Interstellar uninstalled, but reappears when I do. The problem is present in both the x86 and x64 versions. For the x86 version, memory does not appear to be the issue (unless I'm multitasking)

Provided below is my modlist. All are up-to-date (to my knowledge) unless specified.

i had that problem and it was Tweakscale 1.47 & 1.46 which caused it. however, i use 1.44 just like i see you do and it works fine. so i'm not sure that might be your problem. try removing tweakscale and see if your air intakes attach otherwise you've already found the culprit... interstellar - try using the interstellar lite version maybe
