Its been a while since i used the subassembly function. But I made a lifting staged and saved as a subassembly.
Root part is the decoupler. Then i add the subassembly to my upper stage and then the trouble begins.
The subassembly clicks on fine and my craft looks done. But for some reason everything relating to altering the craft locks up.
I cannot grap parts off the craft anymore, i cannot add more, i cannot click the action's menu, i cannot swap to crew menu. I cannot toggle snap or change symmetry anymore. Basically it looks like i cannot do
I can click different parts categories but cannot "pick up" the parts, and I can use the menu to start new, load, launch etc. and I can change staging.
Is this a know bug, or did something change since I last used subassemblies? Years ago.
