Can't get rid of a Tree that was 'Set as Head' and 'Reset Object' while off lot.

SUPER late reply, I apologise BUT I have succeeded in destroying the tree! Hallelujah! So it was quite silly of me because I never play with custom mods or scripts. I had the Custom Mods On but not the Script Mods and I realised after seeing the T.O.O.L Mod had a script menu section as it appeared in my Sims 4 Main Menu. It was a big EUREKA moment! I'm super happy. And thank you for coming to my rescue again. Really really appreciate it!
