By accident I planted a tree in the wrong place and didn't notice I planted it there. 10 days passed and i finally noticed it. The tree is stage 1 and it won't grow anymore (I removed all obstacles around it and it is planted in it's right type of terrain ad waited for another 10 days).
I said "ok, let's remove it then....". To my surprise, I couldn't do it. Technically, the tiny tree doesn't exist (it's hitbox doesn't show up when I toggle HIDE ALL option).I placed objects over it, plow the land below it, pave the land below it....and nothing !!! the little bastard is still there !.
So....my conclusion, this is a design fault, Loftar and Jorb must re-code this !!!. LET US CHOP THE TINY TREES !!!!.
