wierd game breaking bug(or something)

[noobsrtoast]

so in ksp I have a few mods that were working find last time I used them with no noticeable issues, haven't updated since then either, but suddenly and annoyingly I have been getting this bug where when I place a command pod so I can start building my ship in either the VAB or SPH, the game acts like im still selecting a command pod and I cant build, it works fine if I load an existing ship but even then once I place parts I cant pick them up again its seriously annoying and I cant play
